Nor

[matt999tye]

I am writing a program that performs a NOR function and i keep getting this error I cant figure it out!

1>z:\assembly\p2a\p2b\p2b\p2b\p2b.cpp(28) : error C2443: operand size conflict
1>z:\assembly\p2a\p2b\p2b\p2b\p2b.cpp(29) : error C2443: operand size conflict
1>z:\assembly\p2a\p2b\p2b\p2b\p2b.cpp(30) : error C2443: operand size conflict
1>z:\assembly\p2a\p2b\p2b\p2b\p2b.cpp(31) : error C2443: operand size conflict
1>z:\assembly\p2a\p2b\p2b\p2b\p2b.cpp(33) : error C2443: operand size conflict

You should be using unsigned long, not double.

In either case, VC++ could have a problem correctly identifying the size of the operand inside the __asm block. I don't know enough about VC++ __asm to be sure, though...

It might be worth pointing your professor to MASM32.

Hope this helps.

ITS OK! i got it it is because i should have used int!
