Command Line Arguments
By Bill T.

Here is a sample function which shows how to get the command line 
arguments only from the GetCommandLine API function.  The GetCommandLine
API function by itself returns the full command line, meaning the
executable file's name as well as the parameters.  This function is a 
simple method to retreive the arguments only.  


; GetCommandLineArgs
; function to get the command line parameters only.
; returns: pointer to the argunments string 
;          or NULL if there are none 

GetCommandLineArgs proc USES esi 
    call  GetCommandLine 
    mov   esi, eax  
    mov   al, [esi] 
    cmp   al, 22h  	;22h = " 
    jz    loop1 
    xor   eax,eax 
    jmp   return 
;if path is delimited by quotes, there are parameters.
loop1:  
    inc   esi 
    mov   al, [esi] 
    cmp   al, 22h 
    jnz   loop1 
    inc   esi 
    inc   esi 
    mov   eax,esi  
return:  
    ret 
GetCommandLineArgs endp
