Could someone tell me how I write to ASM files in FASM where the first one calls far procedures from another one?
I just look for something like:

Code:

MAIN.ASM:
segment main use16
call far printABC
mov ax, 4C00h
int 21h

SUB.ASM:
segment subroutines use16
printABC:
mov ah, 2
mov dl, 'A'
int 21h
mov dl, 'B'
int 21h
mov dl, 'C'
int 21h
ret

What is the correct syntax to:

why not use include 'sub.asm' directive, and/or make printabc a procedure?

...
...
call printabc
...
...

proc printabc
...
...
...
endp

Thanks for replying, but the point is I'm a student and we are ment to use far calls to other segments. Also proc is not a FASM keyword, is it? How would I do this in plain FASM syntax?
Can I also link object files into the program so i do not always have to include them?

Raw solution without any macros:

SUB.ASM:

Code:

segment subroutines use16 
printABC: 
mov ah, 2 
mov dl, 'A' 
int 21h 
mov dl, 'B' 
int 21h 
mov dl, 'C' 
int 21h 
retf

MAIN.ASM:

Code:

format MZ
entry main:start

segment main use16 
start:
call far subroutines:printABC 
mov ax, 4C00h 
int 21h

include 'SUB.ASM'

Clear and sharp! Now I get it. With the include directive, linking two seperate files is like cutting paper with a chainsaw.
