VidiEditor (Software and documentation by T. E. Kennington.)
           (C) T. E. Kennington                December 1987







1 INTRODUCTION

VidiEditor   is   a stand alone teletext editor and carousel
display  system.  There are two versions of the program. The
first is a  RAM  image  that can be called from disc and the
second is a ROM image that will run from sideways RAM or may
be blown into an EPROM. The  RAM version is smaller and some
of its commands are separate overlays.

If running on a model B, it  must  be  a production standard
model with OS1.2 and DFS. Because the program "steals" space
from  the  DFS  work  space,  it  is important that ADFS and
Econet are not present. If using Econet,  it  is recommended
that the ROM image be blown into a 2764  EPROM and installed
in the computer as a language ROM. The ROM image can be used
from any SWRAM bank  on  a  Master  series computer. (But no
TUBES.)


VidiEditor is capable of storing  up to  20  pages in memory
(one magazine) using easy to use commands and  of displaying
them  sequencially  with a choice of two display times which
may be set  within  the  range 1 to 99 seconds. Links can be
added to magazines to enable a "daisy chain" of magazines to
be displayed.

A   magazine   consists  of  20  1kbyte   pages   and  so  a
maximum of 4  magazines  may   be  stored  on  one  100kbyte
disc. In  theory  five magazines  should  be  the maximum (5
x 20 = 100) but 2  sectors  of the disc are reserved for the
catalogue thus there is not quite sufficient room for 5 20kB
magazines.


2 Getting started

Insert the VidiEditor  disc  in  drive 0 and type "*VIDIED".
Alternatively,  load  the  ROM image (RVidiEd)  into  SWRAM,
press BREAK and then type "*VIDIED".

The   screen   should   then   be    displaying   the  title
"VidiEditor" with a list of  commands.  The  message "READY"
appears  and  command  mode  is  entered. If no  title  page
appears  and  "<$-Not  found" shows at  the  bottom  of  the
screen, then the file  "F_T"  is not present on the disc. It
will not affect the operation of  VidiEd in any way if it is
missing. The following commands are understood:

CAROUSEL  CLEAR    CLM   DISPLAY    ERASE      HELP
INSERT    LINK     LOAD  MAGAZINE   OVERLAY    PRINT
QUIT      REPLACE  SAVE  TIDY       TIME       *<OS command>

The command line is  not  case sensitive and commands may be
entered in upper or lower case.  When  run,  VidiEditor will
switch off CAPS LOCK automatically.

To enter the editor, press  the  cursor  UP key. The cursor,
will move up one line. The position of  the  cursor is shown
at  all  times, in decimal,  by  the V-H  indicator  on  the
command   line.  The  command  line  will  also  be  showing
"edit-normal      ->   <  >  &nn  Vnn  Hnn".  The  character
shown  between  the angle brackets '< >'  is  the  character
under the cursor  or  a  mnemonic  of a control code .   The
ASCII number of the character is shown,  in  hex,  after the
ampersand  (&). This is for use in identifying control codes
and graphic  characters.  The  top  row   of  the screen  is
used  for  the  page  name which should  be  typed after the
colon.(:)  Anything  typed   on   the  keyboard  appears  on
screen.  The arrowed  editing  keys   may  be  used to place
the cursor in any desired position. The delete  key  deletes
as expected and in combination with a shift key will produce
a cube shaped character or "blob".

The  screen will need to  be  "saved"  to  enable  it  to be
recalled.  The  command  -  INSERT  will place a copy of the
screen  in  memory.  Before this,  however,   it  must  have
been  given a 'name' to identify it. This should be typed on
the top  row,  after  the  colon. Pressing  ESCAPE  now will
return to command mode. It is  also  possible  to 'name' the
page at this  point  by  typing the name after  the  command
INSERT. e.g. INSERT TEST, will add TEST to the top row.

The  message "Action successful" will have appeared.  Typing
MAG  will   show   the  magazine  title and the index, which
will now include the page you  have just inserted. To recall
the page, simply type DISPLAY <name> which  in  the  present
case will be TEST. e.g. DISPLAY TEST [RETURN].

At   this   point,   it may be worth mentioning that all but
one of the commands  may  be  shortened to its first letter.
The  exception is  CLEAR which  must  be   typed   in  full.
Also, the  name  may  consist  of only as many characters as
necessary to uniquely identify the page.  Taking our example
above, to display, the minimum  command  could be  -  D  T .
Commands may be written in upper or lower  case,  VidiEditor
treats them the same.

It  will  be   necessary to save the pages  you have created
permanently on disc. This  is  done  by  saving  the  entire
magazine   under   a  'title'.  For instance, if we call our
magazine "EXAMPLE" then typing:

SAVE  EXAMPLE [RET]

will  put  it on the  disc  as  a  file  called EXAMPLE. The
title cannot be more than seven characters long if using DFS
or   ten   for  any  other  filing  system.  (Filing  system
dependent.)  In  the  DFS  disc  catalogue it will appear as
D.EXAMPLE  because  all  VidiEditor magazines  are   put  in
directory D. All other  filing  systems will use the current
directory. (See Disc User Guide for details of directories).
At  some future time, the magazine  EXAMPLE  may be recalled
by, first putting the disc containing the  magazine  in  the
disc  drive, then typing:

LOAD  EXAMPLE [RET]

Typing  MAG next will show the contents of the magazine just
loaded. Having  now  loaded  the magazine, it is possible to
display them in rotation in  a  CAROUSEL. By typing CAROUSEL
on the command line, the command line  will  disappear and a
"header  row" appears on the top line. Unless the  date  and
time have  been  set previously, there will be a blank space
followed by the wrong  time. These can both be set using the
TIME command. Two display speeds are available and these may
be set to anything between  1  and  99 seconds. See CAROUSEL
for  more  details.  You  should  now  be  able  to  "drive"
VidiEditor in a limited form.

2.4 Storing single pages or frames

On occasion,  it  is  useful  to be able to store individual
pages on the disc. Although a  40 track disc can only hold 4
magazines, there is still room for upto 19 individual pages.
These   pages   can  contain  generic  graphic  headers  for
instance,  into  which  text  can  then  be typed to produce
teletext pages as in CEEFAX and ORACLE.

The method involved is to use a qualifier  with the LOAD and
SAVE  commands.  Screen  files are no longer than &400 bytes
and by convention are  stored in the F. directory on DFS. To
load a single frame, use the command:

LOAD /S <fileName>

Similarly, to save the current screen to a file type:

SAVE /S <fileName>


2.5 Using single pages

The idea behind saving  single  frames  is  that  generic or
common  headers  or backgrounds can be used independently of
the current magazine  contents.  The general technique is to
call a frame to the  screen from the disc, fill it with text
or whatever then insert it in the magazine with a page name.
To  do  this, it is assumed  that  there  are  known  frames
existing on your current working disc. (As explained above.)

Lets say we  want  to use a frame called F.HEADER into which
we want to put some text. Type the following:

       l /s F.header [RET]

The frame should now be  on  screen.  It is also possible to
add  a frame to existing pages within the  magazine.  It  is
assumed that  the  text  has been written in anticipation of
having a header added at  later  stage. That is to say, room
has been left for a header! Carry out the following stages;

       Call the wanted header to the screen. (As above).
       OVERLAY the text page from the magazine.
       Give the page a name. (Use the old name.)
       REPLACE old name or INSERT new name.

Don't forget to SAVE the magazine when you have finished!

The   following   section  gives  complete  details  of  all
VidiEditor commands.

3 REFERENCE SECTION (Commands)

3.1 The EDITOR

The screen editor is entered by pressing the  cursor UP key.
To  exit the editor and return to the command   line;  press
[ESCAPE]. On entering the editor, the command line shows;

   edit-normal     ->  <  > &nn V01 H00

and  a   colon  is  deposited in the top left of the screen,
irrespective of what else might  be  there. This is the page
identification  marker. The  cursor is then at V23 H00. i.e.
The cursor is at the bottom of the screen. Editing functions
are listed below. They involve  the  cursor   keys  together
with  the  SHIFT  and  CTRL keys. The cursor  keys  will  be
refered to as LEFT, RIGHT, UP and DOWN:

   1) SHIFT+LEFT  :delete character under cursor  and  move
                   rest of line  left.
   2) SHIFT+RIGHT :move   line  to   right   from  cursor,
                   inserting a space under the cursor.
   3) SHIFT+DOWN  :move screen to the right and below cursor
                   down one line. No part of the screen to
                   the left of the cursor is changed.
   4) SHIFT+UP    :move screen to the right and below cursor
                   up one line, deleting the remainder of
                   the current line.
   5) CTRL+RIGHT  :delete to end of line.
   6) CTRL+LEFT   :delete from begining of line.
   7) CTRL+DOWN   :swap the remainder of this line with the
                   part below it.
   8) CTRL+UP     :swap the remainder of this line with the
                   part above it.

To move whole lines, therefore,  the cursor must be  in  the
extreme left  position. The cursor will  not  attempt  to do
anything  silly.  e.g. It is impossible to swap downwards if
the cursor is on the bottom line.

The TAB  key  is  used  to  change  cursor direction. On the
command  line,  left of the character mnemonic is  an  arrow
pointing to the  right.  This  is  the  normal direction for
typing.  On  pressing  TAB,  the  arrow  points  upwards and
anything  typed  will  be arranged vertically. Each press of
the TAB key moves the arrow and hence cursor direction by 90
degrees anti-clockwise. NOTE: Do  not  attempt  to  use  the
delete  key  in any direction other than normal as it is not
sensitive to cursor direction!


The  red function keys carry  colour  and  graphics  control
codes. These are in f1 to f7 inclusive as below:

  f1      f2       f3       f4       f5        f6      f7
  RED    GREEN   YELLOW    BLUE    MAGENTA    CYAN    WHITE

The RETURN  key always puts  the  cursor at the beginning of
the next line down.   Single alpha colours  are  obtained by
pressing SHIFT and a colour key together. Similarly, graphic
colour  codes   are   obtained   by   pressing  CTRL  and  a
colour   key  together.  Other  control  codes are  obtained
from  the normal keys in conjunction  with  the  CTRL key as
follows:

  CTRL+P   Double height
  CTRL+L   Normal height
  CTRL+C   Clear screen
  CTRL+H   Flash
  CTRL+I   Steady
  CTRL+J   End box
  CTRL+K   Start box
  CTRL+]   New background
  CTRL+\   Black background
  CTRL+X   Conceal display
  CTRL+Y   Contiguous graphics
  CTRL+Z   Separated graphics
  CTRL+^   Hold graphics
  CTRL+`   Release graphics

Graphic  characters   are  entered  from  the  keyboard. All
numeric keys, with and without SHIFT, and  lower  case alpha
keys  will  produce  graphic  characters following a graphic
control code. Alternatively, a "graphic  patch" facility may
be used. Function keys f8, f0 and f9  are  used   with  keys
Q,W,A,S,Z and X. On pressing CTRL+f8 the command line shows;

   edit-graphic []  ->  <  > &nn Vnn Hnn

The  six  keys  Q  to   X  may now be used to toggle the six
bits of the graphic character  on and off. The character may
then   be   inserted   on the screen  by  pressing  CTRL+f9.
Alternatively, CTRL+f0 may be  used to insert as f9 is close
to the BREAK key on  a model B. No other keys respond except
the cursor and colour control keys.  To  return  to  normal,
press CTRL+f8 again or ESCAPE.

Although  <start  box>  and  <end  box> can be used, the BBC
computer is incapable of marking their  presense  and so the
use of these  codes  is not recommended.

3.2 CAROUSEL

CAROUSEL  is the command for  "display  rolling  pages".  On
entry,  the  command   line  is removed, the cursor switched
off and the title row  is  replaced  with a  display  header
row  containing  the  SERVICE  NAME, DAY/DATE and TIME. Each
page held in the magazine is displayed, in order, for thirty
seconds or ten seconds  depending   on  the   type   of page
identifier used. The page identifier is a colon (:)  or star
(*)  that  appears   in  the  top  left  of  every  page  in
the magazine. The colon  is the default character and causes
a  display  time of  30   seconds   to   be   set.   A  star
inserted in this  position  causes  a  display  time  of  10
seconds  to be set. These times are refered to as "slow" and
"fast" but  both  may  be set to any value in the range 1 to
99. To change the normal (ie. "slow") time of 30 seconds to,
say, 20 seconds, a command of the form:-

  CAR slow=20 [RET]

is used. Similarly, to  change  the "fast" time (as prompted
by an asterisk), to, say, 15 seconds, the command:-

  CAR fast=15 [RET]

should be used.

The display may be advanced to the next page in the sequence
at  any time  by pressing the  cursor  right  key.  Pressing
cursor  left  gives  you the previous page unless you are on
the first page of  a  magazine. The display can also be held
static on the current page by  pressing  the  space-bar. The
time  in  the top left hand corner of  the  screen  is  then
replaced  with  the  word  "HOLD"  in  green,  exactly as on
teletext  receivers.  To return  to  normal,  press any key.
The   display  will  immediately  advance  to the next page.
[ESCAPE]  returns  to  command  mode.  When displaying,  any
"holes"   (i.e. erased pages) are skipped  over.  After  the
last page  has been displayed, the pointer is reset  to  the
first page  and  the  cycle  continues.

If a link  is  present  in  the  magazine, then the carousel
automatically loads  the  next  magazine  and  continues  to
carousel. In a linked chain, the last magazine should always
link  back  to the first to maintain continuity. (See LINK).
If there is no magazine present, then a beep is made and the
error message "NO  MAGAZINE" flashes on the command line. No
attempt is made to display.

  Changing the SERVICE name

The service name is the  first  part  of the header  row  in
CAROUSEL.  The default value is "VidiFax Carousel". This may
easily be changed at any time by  the  command:-

  CAR = <new name>  [RET]

The new name follows the equals sign.  Thereafter,  your new
name  will be used instead of "VidiFax". It will  remain  in
use  even   if  VidiEditor  is terminated  and  subsequently
recalled.  The  default   name  will only reappear after the
machine has been switch off and on again.

As a further option, the header row can be completely blank.
The command:

  CAR Hoff [RET]

will turn the header row off and enter the carousel. It will
stay off for all subsequent calls to the carousel. To resore
the header, use;

  CAR On [RET]

The header will remain on  for  all subsequent  calls to the
carousel.

3.3 CLEAR and CLM

Clears  an  entire magazine from the index  enabling  a  new
magazine  to be   created.  This command should be used with
care because of the  way  it  works.  It  does  not actually
remove  the  magazine  from the memory but instead  modifies
the  page  identifier (the colon). Thus until further insert
operations, the pages  of the magazine still exist  and  may
be recalled  by  name  or the whole magazine may be restored
by repeating the command.  It  can  be  seen  therefore that
CLEAR has a toggling action on the page identifier.  Its use
is  in  removing  a  magazine  after  it has been completely
filled  and  saved   and   the  user  wishes   to   continue
creating more pages.

Some times it may be required to flush the magazine entirely
from memory. This can be achieved by the command:

CLM

There is NO recovery from this command so use with care!


3.4 DISPLAY <name>

Calls   a   page  from  the magazine (not disc) and displays
it on screen. The name is the name of the page as it appears
in the magazine  index.  A  space MUST follow the command in
order that the system knows where  the  next word (the name)
begins. The  name does  not  need  to be given in full; only
the number of characters to uniquely identify the  page.  If
the  page   cannot   be  found,  the  error message "No such
page" is given.

Alternatively, a page may be  displayed  by  refering to its
number as read from the magazine index. The page number must
be  enclosed  in  parentheses.  e.g. To display the eleventh
page in the magazine, the command:

  DISPLAY (11) [RET]

is used. This command is used for displaying pages  that may
have  been  inserted  without a name. To display a page that
has just been erased,  (perhaps  by  accident)  then  use  #
(hash) for the name. To display a temporary page, created by
*  or SAVE commands then use / (oblique) in place of a name.


3.5 ERASE <name> or <name1:name2>

Removes  one  or more pages  from  the  magazine.  The  page
identifier is removed and the first character of the name is
changed  to  #  (hash).   The  next  INSERT  operation  will
over-write this page.  Until  then,  this  page may still be
displayed by using #.    e.g. D # . Pages may also be erased
by  numerical  referance.  e.g.  ERASE  (12).  (See  DISPLAY
above.)

To erase  a block of pages type a colon after the first page
name or number  followed  by the LAST page name or number in
the block you wish to erase. e.g.:

ERASE apples:bats   or     ERASE (8):(14)

If the page cannot be found, the  error message :-
"No such page" is given.

3.6 HELP

Not  implemented  on  the  current  version  of  VidiEditor.
However, a short form guide  is  provided in the form of the
F_T file which is displayed when VidiEditor is first run. On
ROM versions, this is displayed after typing  "HELP".  A  20
page  magazine  called  HELP  is  available  as  part of the
system. Load as a normal magazine and use  CAROUSEL  to view
it.

3.7 INSERT <name>  or <(no.)>

Stores the page  currently  on screen in the magazine. On  a
successful   transfer,  the message "Action  successful"  is
given. The page  must  be  given  a name by which it  can be
found again. It can be added to  the  top  row whilst in the
editor or it can be given on the command line. e.g.:

   INSERT TEST PAGE [RET]

This will add "TEST  PAGE"  to  the top row before inserting
it  in the magazine. Note that it  will  over-write anything
already there. A colon is always put at the start of the top
row  to  act as the page identifier.  This is  essential  in
order that the  system  knows where to put the next page  to
be  inserted. The pages are  stored  sequencially  until the
magazine is full.

Pages  may  also be inserted to specific slots by using page
numbers. So, for instance, the command;

IN (10)

will insert to  page  10  if  it is free. If page 10 already
exists, the error message "Page exists" is  given.  It  will
then  be  necessary  to ERASE (10) or REPLACE (10). The page
name can be included with this command. e.g.:

IN TEST PAGE(19)

will name the page TEST PAGE and insert to slot (page) 19.

If  all  20  pages  are  occupied, then  the  error  message
"Magazine full" is given if an attempt to INSERT was made.

3.8 LINK <title>

In VidiEditor, one  magazine  of 20 pages can be held in the
memory. This may not be sufficient room for the users needs.
However, the command LINK can  be  used  to  "chain" another
magazine, previously stored, onto the carousel. It takes the
form:-

  LINK <magazineTitle>

Drive 0,  directory  D are assumed but other directories and
drives may be part  of  the  magazine  title. After the link
command  has  been used, it will be necessary  to  SAVE  the
magazine so that  the  link  is  also saved. LINK on its own
removes  a link but again, this only  affects   the  current
magazine. Any  number  of  magazines may be chained, subject
only to the storage capacity  of the system. eg. On a single
40  track drive, 4 magazines or  80  pages  can  be  stored,
whereas on  a twin double sided 80 track drive, 36 magazines
or 720 pages  may  be  stored.  If  a link is present, it is
shown in the MAGazine index.

3.9 LOAD <title>

Loads  the  specified magazine into  memory.  Magazines  are
normally 20k bytes  long  and  will  over-write  the present
memory  contents.  In  the DFS disc catalogue, magazines are
always stored in directory D  or  the  current directory for
other filing systems. The title  is  the  file   name. If no
title is quoted then the user will be prompted for one:

Mag.title:

The qualifier '/screen' (which may  be  shortened  to /s) is
used  to  load a single page file directly  to  the  screen.
e.g.:

LOAD /SCREEN F.ETP

will load the file F.ETP  to  the  screen. It is not part of
the magazine.

If the specified magazine cannot  be found on the disc, then
the disc error message "$-Not found" will be given.

3.10 MAGAZINE

Produces  the index of the  current  magazine  in  insertion
order, giving  page  number  and  name.  Only  the page name
between  the  colons  is  visible. If there is  no  trailing
colon, then only the first  29  characters are shown. If the
external  PRINT  routine  has been used then "ptr=<printer>"
will be shown, top left in red. <printer> depends on whether
a printer programmer has  been  used  or  not.  If a link is
present, this will also be shown, on the bottom  line.  Note
that a full file path name is always used and will typically
look like:

   Link := :1.NEXTMAG  or perhaps   LINK := mag.Wildlife

The second example is only valid for ADFS or Econet.

3.11 OVERLAY <name>

Copies  the  specified page over the current one. Where ever
there is a  space  in  the  foreground  page (the one  being
overlayed)  the  background  will remain unchanged. The page
name remains that  of  the background. This does not  affect
the magazine; the page should  be treated as  if it has just
been  edited. If the specified page  cannot  be  found,  the
error message "No such name" will be given.

3.12 PRINT <name1>:<name2>

Prints out the pages <name1>  to  <name2> inclusive on an 80
column printer such as the Epson RX80.  If  only  the  first
name is  given, then just that page is printed. To print the
current  screen  contents, the qualifier "/S" can  be  used.
e.g.
    print /s

All graphics are replaced with ***. Pages are printed 4 to a
sheet on standard  66  line (11 inch) fanfold sheets. If the
utility "VPP" (system disc) has been used to program an FX80
or similar printer then graphics  can  be reproduced and six
pages per sheet are printed.

NB.:   Double   height  and  separated  graphics  cannot  be
reproduced.

3.13 QUIT

Finds BASIC and resets the computer.

3.14 REPLACE <name>

Finds the specified page and inserts the current page in the
magazine in place of it.  If  the  name  is  left out of the
command,  the  name  currently  on the top row will be used,
UPTO THE FIRST SPACE  ONLY.  If  there is more than one page
that begins with the same word, therefore, it is wise always
to  specify  the  full   name in the  command  or  use  page
numbers. (In parenthesese).

If the specified page cannot be found, the error message "No
such name" will be given. No  further  attempt to insert the
page will be made. If the page was  found, then the original
page will have been overwritten by the current one  and  the
message "Action successful" will be given.

3.15 SAVE <title>

Saves a magazine of twenty  pages  (including blanks) to the
disc. The title will be the  file   name  and   it  will  be
in   the   disc   catalogue in the current directory or D if
DFS is used. If  there  is  insufficient  room  on  the disc
to  hold a 20k file (one  magazine),  the disc error message
"$-Disc full" will be given. A 40 track  disc can hold  upto
4  magazines  per side whilst an 80 track disc can hold upto
9 per side. (DFS format)

If the title  is  not  specified, the current magazine title
(if present) is used. This allows a magazine to be regularly
saved to disc without having to bother about file names.

The  current  screen  may be saved as a file  by  using  the
qualifier "/s". e.g.:  (in full)

SAVE /SCREEN F.MESSAGE     or     s /s F.message

3.16 TIME

TIME is  used  to  set both the internal clock (as in BASIC)
and also the "day/date" string  which appears on the  header
row when using CAROUSEL. On entry,  the  screen   clears and
the   current  time  and  day/date,  if any, are shown. On a
Master computer, the time and day/date  will  have been read
from  the  Master's  real time clock which saves  having  to
enter it manually. On  a  model  B, the time and day/date is
unset.

You  are asked if you wish to change the time:

        Change time? (Y/N):

Answering   with   "Y"   will  present  separate headers for
hours,  minutes  and seconds. [RETURN] must  be  pressed  to
enter  each  value.   A   null value,  i.e.  [RETURN] on its
own, is considered to be  zero.  After the seconds have been
entered or "N" was the answer to the question then:

        Change date? (Y/N):

appears. Answering with "Y" causes:

        Enter day/date >          <

to appear.  Anything  typed  between the angle brackets will
appear on the header row  in CAROUSEL. The normal format, as
used by CEEFAX and ORACLE, is of the form:

        DAY DATE MONTH                   e.g.>Sun 19 Aug<

Anything typed beyond the second angle  bracket is  ignored.
After  pressing [RETURN] or the question was  answered  with
"N" the screen reverts to whatever was on it before TIME was
called and  the  cursor  returns  to the command line. NOTE:
THIS  WILL  NOT  OCCUR  with  disc   versions  as  there  is
insufficient memory to store the previous page.

3.17 X

This is a simple diagnosic.   Since  it is not  possible  to
see control codes on the BBC computer,  this  command may be
used to mark them. The cursor may then be  placed  over  the
same area  when  the  page is recalled and the ASCII number,
in HEX, may be read from the command  line,  after  the  "&"
symbol.    "X"    works    by  scanning   the   screen   and
replacing   all  control  codes  with  "@".  To  replace the
control codes, type DISPLAY /TEMP.

This facility is also  available  from  within the editor by
pressing function key f8, where it has a toggling action.

3.18 *<operating system command>

This  is  exactly  the  same  as  star  commands  in  BASIC.
Everthing after * is passed  to the operating system. Before
this happens, the screen is stored  in  the temporary memory
and the screen is cleared for use by the operating system if
necessary.  One  of the most  common commands, for instance,
is *CAT. This  displays  the  disc  catalogue on screen. All
errors  from  the  OS and filing systems  are  reported  and
control always returns to the VidiEditor command line.
