I was wondering if there was a way to insert Machine Code into a GPC Program. The reason is that I'm trying to duplicate Borland Pascal's Port array by using 2 functions, one for port input, one for port output. My problem is that when I type "asm( 'inb %al, %dx' );" the compiler says "386 instruction not recognized" I tried using an INLINE statement, that didn't work either, I even tried "asm( '$EC' );" which is the machine code equivalent, still nothing, then I tried "asm( 'db $EC' );" which didn't do it either. I understand that GPC was meant to be cross platform, but I need port access. I also know that I could link it externally, but I don't want to have to do that unless it's absolutely necessary :( Thanks in advance!
See ya! Orlando Llanes
