Using GPC's asm statement allows us to set the function result with an ASM statement, but how do I set the result of a function through an external assembly routine? The Assembler I'll be using is NASM (just in case you need to know). Thanks in advance! See ya! Orlando Llanes "Meine Damen und Herren, Elvis hat soeben das Gebaeude verlassen!"
