The following is a method of unpacking a compressed file compiled into 
the .exe file as a resource.  It makes use of Jeremy Collake's MASM 
compression libraries found at (http://www.collakesoftware.com/).  Please
note that "dialog.txt" is the product of pre-compressing another win32asm 
application previously made for example. 

My version works as one stand-alown exe:

RESOURCE CODE:

500 ICON MOVEABLE PURE LOADONCALL DISCARDABLE "MAINICON.ICO"

MOSTUFF RCDATA dialog.tst  /* this is the compressed data */

600   MENUEX MOVEABLE IMPURE LOADONCALL DISCARDABLE
BEGIN
    POPUP "&File", , , 0
    BEGIN
        MENUITEM "&Open", 1000
        MENUITEM "", , 0x0800 /*MFT_SEPARATOR*/
        MENUITEM "&Decompress", 1001
        MENUITEM "", , 0x0800 /*MFT_SEPARATOR*/
        MENUITEM "&Exit", 1010
    END
    POPUP "&Help", , , 0
    BEGIN
        MENUITEM "&About", 1900
    END
END

Well there it is when added and ran, this exe file succesfully decompresses
the resouced data stored within itself into another .exe file that will
run perfectly.
