I thought I only needed to code "ret", and the memory
model would take care of converting that to either
retf or retn, as required.

But I found under both wasm and masm I need to put
retf. Any idea why?

..model medium

..code

public two
two:

push dx
mov ah,2
mov dl,41h
int 21h
pop dx

retf

db 40000 dup(?)

end

Thanks. Paul.

I found that if I put it in a proc, it behaves as expected.

..model medium

..code

public two
two proc

push dx
mov ah,2
mov dl,41h
int 21h
pop dx

ret

two endp
