This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

                               HELPFILE


          If,  like me, you have an unreliable memory you are probably
fed up with constantly searching through the various  advance  manuals
available  for  the  B.B.C.  looking for confirmation of something you
should know but could not quite remember the exact syntax of. How much
more convenient it would be if all the most important facts  could  be
available  as  *HELP  information. Loaded into a sideways ram bank and
ready to be displayed at any time. If you have more than one  bank  of
sideways ram, as many BEEB users now do, you could have multiple banks
of helpfiles booted up ready for any programming session. 

          The  HELPFILE  program  can  be  used  to  create  your  own
customised sideways ram *HELP facility. On  running  the  program  you
will  be  presented  with  a menu, to start creating your own helpfile
choose option 1, this sets up a random access disc file which will  be
used  to  store  the  data  needed to create the final rom image. This
random access file is broken up into  sections,  one  for  each  *HELP
command,  you can see them being counted off on the screen as the file
is created. When the count reaches the maximum number of  files  (150)
you  will  then  be  presented with the editing screen. Note that this
file is nearly twice as long (almost 32K) as the maximum size  of  rom
image  being  created (16k), this is because each command is initially
allowed message space of 5 lines of  40  characters.  When  the  final
helpfile  is  created  all the unwanted spaces are removed, the editor
includes a byte count constantly updated on the screen to help you use
the available space efficiently.

                                EDITOR

          The editor is entered at command number 1, you will see  the
cursor on the command line, below this there are 5 lines for typing in
the message to be displayed. At the top right the number of bytes left
is  displayed,  this  should  read 16157 for a new blank file. Use the
cursor keys to move around the screen, anything typed will  either  be
inserted  at the cursor position or will overwrite current text at the
cursor position. You can toggle between insert and  over  modes  using
the  <COPY>  key,  the current state of this switch being displayed at
the bottom right of the screen. Commands have a maximum length of  ten
letters  and are automatically restricted by the editor to upper case,
numbers and the characters:-  /<=>?@[\]^_#  i.e.  characters  numbered
from  47  to  96.  This  is not only to eliminate characters which BBC
Basic  might  misinterpret  but  also  because  *HELP   commands   are
automatically  converted  to upper case and would not be recognised if
the rom image  contained  lower  case  commands.  The  actual  message
displayed on the screen is not limited in this way and can contain any
typable character, i.e. character numbers 32 to 126.

          Each line of text has a line limiter at the end "|", this is
there so that you can "see" any blank spaces on a line. The bytes left
count  is  automatically updated as you type, but you will notice that
if the command line is empty then this count  will  remain  unchanged,












this  is because when the final rom image is created all zero commands
are ignored. Similarly all zero message lines will be ignored, if  you
wish to space out your messages then you will have to put at least one
blank space in the line between the messages. You can continue to type
even  when  the bytes count is minus, though if you do not go back and
edit other commands to return the byte count to positive then when the
helpfile is created you will lose any surplus commands. The routine to
create a helpfile includes its own byte count check  and  will  ensure
that  there  is  enough  space  left before encoding each command, you
should never end up with half a message tacked on at the  end  of  the
file.

          When  you  have  finished the first command press <TAB>, you
now have the choice of either pressing <RETURN> to go  onto  the  next
command,  or  entering  the  command  number  you wish to edit next or
pressing <ESCAPE> to return to the menu. On pressing  <TAB>  the  data
you have just typed in will be stored on disk in the data file, you do
not  have  to create the whole rom image in one sitting, any data file
can be edited one command at a time at  your  convenience  using  menu
option number 2. You can type in and edit commands out of order as any
blank commands will be ignored.

                         CREATING A HELPFILE

          Choose  option  3  and  enter  the  filename  to be used for
creating the finished rom image,  this  must  be  different  from  the
filename  for  the  datafile from which the final helpfile is created.
Next enter the datafile filename and you will see the  commands  being
counted  off on the screen. When this process is finished you can exit
the program and load the helpfile into sideways ram, you will need  to
press  <BREAK>  to initialise it. This should display the name of your
helpfile along with  the  normal  startup  messages.  Now  type  *HELP
<RETURN>  and this same message will be displayed, any message can now
be displayed by typing *H.(COMMAND) <RETURN>.

                      OPERATING SYSTEM COMMANDS

          Any * command  can  be  entered  from  the  menu  either  by
choosing option 4 or typing <*>. The program includes a *FX180 command
which  sets  OSHWM  (operating  system  high water mark) to an address
above the area used by the program. This means that any command  which
would  normally  corrupt the program area, such as *BACKUP or *COMPACT
can be issued from  within  the  program  in  complete  safety.  These
commands  use the area from OSHWM to HIMEM as an extended disk buffer,
OSHWM is normally set at the same address as PAGE  thereby  corrupting
any  program  or  data stored above PAGE. Setting OSHWM above the area
used by the program sets up a safe buffer area, this buffer is smaller
than usual so *BACKUP will require more passes and  will  take  longer
than usual. If you use this idea in your own program be careful not to
issue  the  O/S  command  from  within  a procedure or function as the
return addresses and local variables used by PROCs and FNs are  stored
on the stack below HIMEM and could be corrupted. If you are creating a
helpfile  with  many  repetitive  messages  then  you can enter a *KEY
command to setup the function keys to type these parts for you.













                            COMPATIBILITY

          This program has been tested on a BBC  B  with  an  issue  7
board  and  O/S 1.2/ACORN DFS 1.2, using Solidisk's 2MHZ 256K sideways
ram (with and without a 6502 second processor). It has also been  used
on  an identical machine fitted with Solidisk's original SWR128 and on
the same machine fitted with Acorn User's 16K UserRAM.  There  are  no
illegal  peeks  or  pokes,  and  only well documented operating system
calls are used so it should work with all BBC type machines  including
the ELECTRON and COMPACT.

                                FXHELP

          Broadcast  with this program is an example helpfile (FXHELP)
together with the datafile used in its creation (FXDATA).  This  gives
help  messages  on  all  the  available  FX  commands,  load this into
sideways ram, press <BREAK> and you should see the message:-

                          Help File : FXHELP

Typing *H.FXHELP  will  display  a  list  of  the  available  FX  help
messages, for example *H.FX0 will display:-

                             Print OS No.

If  you  can create a really useful helpfile why not send it in to the
BBC Telesoftware service for broadcasting?
