    ; --------------------------------------------------------
    ; The following are the same function calls using MASM
    ; "invoke" syntax. It is clearer code, it is type checked
    ; against a function prototype and it is less error prone.

    invoke MessageBox, 0, szCommandLine, 0, MB_OK

    invoke ExitProcess, 0
