And here's yet another one for you:-
Having LRESPRed various extensions in my Boot program, what would
cause
some or all of the resulting EXTRAS to disappear from the EXTRAS
list?
Having run the boot, I have checked the EXTRAS list and been happy
that
what I wanted is there. Then, after allowing the boot program to
call
the next program in the sequence using ex 'win1_next program.exe'
which
subsequently returns on completion, I find that re running the same
boot
program fails since some of EXTRAS are no longer there. What sort of
error should I be looking for?
Is there a way of stepping through a BASIC program, line by line,
for
debugging purposes? If so how?
Two possibilities, albeit remote ones, I can think of:
1. If other jobs were running (including hotkey job) and you used
LRESPR to load the extensions, it would not be able to put the
extensions into RESPR space, instead it uses the equivalent of ALCHP.
When the job is finished, or a NEW issued (etc etc) the heap space
might get cleared and extensions lost. Always best to LRESPR
extensions before you start any other jobs, including SBASICs and
Hotkey jobs (i.e. before a HOT_GO).
2. If you LRESPR an extension into a daughter SBASIC, they might be
local to that job and vanished when that particular SBASIC is removed.
There's a little info about this on the bottom of page 27 (in my
version of the manual at least) of the SMSQ/E manual.
Could you possibly send a few lines of your boot so we can see what's
happening? Or send it to me privately off list?
