[Coco] Programming help

[Bill]

Thanks, Robert, I appreciate the tips, but I've given up on this one. I've
had too many replies to this thread suggesting that I haven't typed in the
entire program, or that I don't have sense enough to read the directions
(not from you, though) and that listing 3 MUST be run with listing 2 in
memory, so I'm gonna quit asking questions about anything. I'll admit I'm
not a programmer, but I do have sense enough to read directions and copy a
listing verbatim.

Thanks

If you are using EDTASM, change NAM to TITLE. However, all that will do is
print 
at the top of each page B256 ; assuming you are assembling to a printer.

You say that you did a LOADM and EXEC which crashed your Coco. That is
pretty 
simple as you did not specify an EXEC address (nor does the listing.) The 
default for EXEC, when not set manually, is $0000 and as there is no code
there, 
you got a crash.

You must change the last line of the listing from

720       END

to

720       END   $E00


If you change the listing so that line 80 reads

80 START  ORCC  #$50

then you could use

720   END  START

EDTASM will accept variables as well as exact addresses for the EXEC
address.

All of this and much more is in the EDTASM manual. Since assembly
programming is 
more complex than Basic, you really should at least skim through the manual
(you 
have been given urls) before walking through the minefield of programming.
