F/+ADCOM2

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.

Toolkit commands are CHAR, COMPACT, FIND, FKEYS, GOODPROG, GREPL,
KILLREM, LGOTO, LLIST, LVAR, MEM, OPT, SORT, SREPL and VERIFY. The
CHAR command provides a simple way of designing user-defined
characters using an 8 x 8 grid. COMPACT is an intelligent line
compacter that will add lines together in a program in such a way that
program execution is not affected - e.g. COMPACT |100,500 will compact
lines 100 to 500 inclusive. FIND|x(|(")s,e) will find  all x's between      
lines s and e inclusive and in quotes if " is used. FKEYS returns the
function keys set. GOODPROG will attempt  to mend  a "bad" program.
GREPL will replace globally any set of characters with any other set
of characters and takes the form GREPL|x|y(|(")s,e). KILLREM (|s,e)
will kill all REM statements between lines s and e inclusive. LGOTO x
provides a structured jump where x is a label in lower case and must
be at a start of a line. LLIST x  will list a line who's number is x,
and can be used in conjunction with FIND and certain OPT commands but
is too complex to explain now. LVARSg will list variables whose  
names begin with S onwards to those beginning with g, and LVARtt will
list all variables beginning with t. MEM will give the spare memory.
There are many OPT commands and again too complex to explain now -
they can be used in the TURTLE GRAPHICS and with foreground and
background effects with CFILL. SORT is usedwith string arrays and SORT
A$(1),A$(5) will sort into alphabetical order elements 1 to 5 of array
A$. SREPL will replace selectively any set of characters with any
other set of characters within part or all of a program, with all
matches being highlighted, and the user specifying whether to replace
or not by keying in "Y" or "N" - it takes the form SREPL|x|y(|(")s,e).
VERIFY will check that the program on cassette or disk is as in
memory and takes the form VERIFY f(,a) where f is the filename and a
the start address if not PAGE.

The miscellaneous commands are POPFOR, POPGOS, POPREP, SETWIN  and
WIN. POPFOR allows the jumping out from a FOR....NEXT loop, e.g.:-
10FOR X=1 to 30
20IF X*X>100 THEN POPFOR:GOTO 50
30NEXT X
40END
50......
POPGOS will delete the current subroutine return address so that a
GOSUB subroutine can be jumped out of cleanly. POPREP is  similar to
POPFOR for use in the REPEAT.....UNTIL loop. SETWIN is used to set up
multiple windows to a maximum of seven, and takes the form SETWIN
w,x1,y1,x2,y2 where w is the window number 1 to 7. The windows are
then selected by the command WIN w. Again a lot can be done with this
arrangement using CFILL and FILL commands and normal BASIC.

ADDCOMM allows command syntax to be obtained quickly such as *H.SCALE.

I keep a separate disk for files using ADDCOMM. ADDCOMM is a BBC ROM
but so far I had not had any problems using it with the Electron,
though it can only be used in 32K mode.

I hope that members who do not have this ROM find the article
interesting and that they then might get one when available. There is
a lot more to the ADDCOMM SUPER EXPANDED BASIC than I can possibly
explain in this little article.
