what is FAR PASCAL?

Question

I was wondering why in some source code there are these macros like FAR and PASCAL. What do they mean and do?

Answer 1

It's probably some redundant / obsolete coding left over from the 16bit era.

FAR was used in 16 bit applications to indicated that the address required more than 16 bits.

PASCAL(altion) is a conversion type, it lets the compiler know how the stack is arranged (using PASCAL calling conventions) so that the compiler can pass the appropriate paramaters to and from the function.
