how to call int86x bytewise pointer
« on: October 01, 2016, 06:35:49 AM »
Hello there,

My problem below:
VCCRT2.EXE Is a Microsoft download, among other files it contains 'INT86X.ASM'. After a bit of fiddling, it compiles for me. I know what INT86X is, that's not my question. But, does anyone know how to call that routine. I'd like an answer without applying structs/unions, but so that i can traverse bytewise (mov ... ptr +1 or +2 or more).

The source I'm speaking of is at: www.pcorner.com/list/CPP/VCCRT2.ZIP/INT86X.ASM/

Thanks, I've been trying hard already.

INT86X is a messy hack that allows you to call a RM interrupt from a HLL. Why use it at all when you can code a procedure in assembly that does the interrupt call cleanly, and call the procedure from your HLL code?

Well Microsoft, here’s another nice mess you’ve gotten us into.
