I am currently re-writing a BBS door game that was originally coded circa 1987. I am looking into adding IGM's to this old game but have run into a small code block. I have completed writing the unit to handle all i/o when the Igm is running, BUT I want to swap the main calling program out of memory to the hard drive when the Igm is run.

I have got it working using the 'Swapvectors' and the 'Exec' commands but
as the main program is slowly growing in size and the called Igm's can also be rather large as well, I need to Swap To hard disk and back again.

Swag has been no help at all. Can anyone assist with a unit that will do what
I want.

cheers Dennis

ok... that should be easy enough...

my first question, since i've never played with IGMs, is are they simply another EXE??

if the answer to the above is yes, then the name Ralf Brown should recall some memories for you... then i'll also say that i have a copy of his 1991 SPAWNO package that i have used (with TP6) in the past with great success...

google and ye shall find :)

they sure are

I doesn't matter now as I have done some research into swapping and coded my own unit, seems to work really well.

Thanks

i wasn't sure... i kinda figured they had to be or some type of overlay system...

ok... JFYI, that SPAWNO library leaves only ~300 bytes of program in memory when it swaps... it'll swap to EMX, XMS, EXTended, DISK or any necessary combination of them... it'll also leave interrupt handlers in place which leaves more (but necessary) code in memory... it is a fantastic li'l package that only adds about 3k to the final compiled exe when all is said and done...

it should work with TP7/BP7 with no problems... i have no idea about delphi, though... i've only written on small app with delphi and spent the most time on
creating a "CRT" type unit to use with porting some of my programs with...

what pascal are you coding with?? have i ever seen you over on irc.bbsnet.org? ;)

oh, ok... i may play with SPAWNO and see about a quick BP7 compiled test tool...

and NO.

i wasn't sure... i know i see other fido members over there... quite many of them, in fact ;) you and i talk to several of them in these areas, too O:)

Really? Was going to suggest Swag. I see 4 files in Swag
alone. Hrm....

The problem though is the platforms today. What the old
code for Exec did for Dos it may not work properly for
Windows. Especially the new restrictive OS of XP and NT.

What I might suggest is using the Delphi version of the
Exit or old swap setups. Do you have Delphi there?
