get a full set of prototypes for ASM in a fast and automated way

 reverser+,

I hope you are well, I am starting to see the small changes you are
making and it is a good idea...

I have pasted in at the bottom, the code for a MASM application skeleton

as I know you have an eye for assembler and I thought you may like the
use of the MASM pseudo/high level syntax. it compiles at 5.5k with a
menu & icon and I have some GDI graphics written into the test piece.

I found that there are no header files from M$ for MASM so instead of
writing them manually which would take years, I have written a special
purpose utility that raeds the function name out of the Platformsdk
libraries and converts them into PROTOTYPES.

It reads them in the form "_FunctionName@12" and converts them to the
form,

BeginUpdateResourceA PROTO :DWORD,:DWORD
BeginUpdateResource equ 

BuildCommDCBA PROTO :DWORD,:DWORD
BuildCommDCB equ 

BuildCommDCBAndTimeoutsA PROTO :DWORD,:DWORD,:DWORD
BuildCommDCBAndTimeouts equ 

CallNamedPipeA PROTO :DWORD,:DWORD,:DWORD,:DWORD,:DWORD,:DWORD,:DWORD
CallNamedPipe equ 

CancelIo PROTO :DWORD etc...

The idea is to be able to get a full set of prototypes for ASM in a fast

and automated way. The template pasted in below uses them. I have
attached the EXE which I hope gets to you. If not, give me a yell and I
will post it on my page for you.
