   Hi SunBeam

   You could define it as a subroutine.
   The drawback is that you can’t use invoke, you are stuck with push and call.

   TrimString:
   push edi
   mov edi,[esp+8]
   .
   mov eax, [esp+12]
   .
   pop edi
   ret 8

   .
   .

   push 5Ch
   push offset dispBuffer
   call TrimString

   After some more testing I came up with this:
   OPTION PROLOGUE:NONE
   OPTION EPILOGUE:NONE

   TrimString proc a:DWORD,b:DWORD

   push edi
   mov edi,[esp+8]
   xor eax, eax
   or ecx, -1
   repne scas word ptr [edi]
   inc ecx
   neg ecx
   dec edi
   mov eax, [esp+12]
   xchg ah, al
   std
   repne scas word ptr [edi]
   add edi, 2
   cmp word ptr [edi], ax
   je @f
   xor eax, eax
   jmp @end

   @@:
   add edi, 3
   mov eax, edi

   @end:
   cld
   pop edi
   ret 8

   TrimString endp

   OPTION PROLOGUE:PrologueDef
   OPTION EPILOGUE:EpilogueDef

   Hello, KetilO.

   The idea wasn’t to do it all MANUALLY Cuz from human point of view, one can easily check stack and adjust parameters. Idea was to alter compiler into checking parameters and directives accordingly and output the correct result given the specified circumstances..

   Hi SunBeam

   Altering masm (the assembler) is not an option. Masm is a Microsoft product.
   It might be possible to craate your own macros for prologue, epilogue, proc and invoke.

   Strangely I cannot change the color of numbers in the code editor under options.

   Hi ally

   It works here.
   Maybe the fact that RadASM has a different color theme for each programing languade has you confused. Use Project / Set Assembler before you change the color.
