HexDecode proc uses esi edi ebx pHexStr:dword,pOutBuffer:dword

Hi,
I do not know if this is exactly what you want since it's a totally noobish solution
(It could also be that I've misunderstood your request, if so I'm sorry):

Code Select Expand

@1:
   movzx edx, BYTE ptr [esi]
   cmp edx,"*"
   jnz @noasterisk
   inc esi
   ;Commented: String will be "TEST"
   ;Uncommented: String will be "T*ES*T"
   ;mov [edi], dl
   ;inc edi
   jmp @1
@noasterisk:
   cmp edx, 40h
