Callback Subroutines or Functions

Guest · Post by **Guest** » Thu Oct 07, 2004 9:30 am

I have recently noticed that QuickBasic does not give the programmer access to the address of user-defined subs or functions (I can find no equivalent to VARPTR / VARSEG).

Has anyone seen an example of a callback routine in QB? Perhaps in the form of an interrupt service routine, or a timer hook? If this doesn't exist, perhaps I'll fiddle around and try to get it going myself.

Sorry, my login session expired as I was composing the question.

Only using some hacking, in pure qb: http://www.geocities.com/av1ctor/files/PQBPPTR.ZIP or in asm: http://www.geocities.com/av1ctor/files/boostqb.zip

Examples inside.. You can create ISR's or whatever, but only if the module is compile, won't work inside the QB's IDE..

Thanks v3cz0r! I was afraid it would require some trickery, and it makes sense that SUB and FUNCTION addresses are not available in "interpreted" mode (running without compiling).
