The following is a 16-bit code i'm trying to run on masm32.

I can't find the error, mind helping me out please :)

I get "There was an Error in Creating." when it runs. What is InputOutputCommand supposed to return in dx?

InputOutputCommand PROC
      ;;;;;;;;;;;;;;;;;;;;;;;;For the Input File Name;;;;;;;;;;;;;;;;;;;;
      mov di, 81h   
      mov si, OFFSET InputFileName   
           
      mov al, 20h
      repz scasb
To use a rep prefix you need to init CX, probably when the file is loaded CX=0 so no rep happens.

Try to check your filenames before using them.

mov di, 81h
mov si, OFFSET InputFileName
mov al, 20h
mov cx, 128 ; see Sinsi's post
push di  ; you need that one, right?
repz scasb
pop di

FileMissing: stc

mov dx, OFFSET InputFileName
mov ah, 9 ; display message the
int 21h ; traditional way
