I need help on a a script!

[Gulliver]

Hi, I am trying to get the following script to do the following:
Check if omniscsi.device exists
else quit this script and run PlayCD
if not exists omniscsi.device then continue with the following part:

IF NOT EXISTS ENV:PlayCDpatch
    SETENV PlayCDpatch=""
    STACK 8192
    RUN >NIL: Playcdkludge 3    ;Unit number of your CD-ROM Drive here!  
    STATUS >ENV:PlayCDpatch COMMAND Playcdkludge
    PlayCD
    BREAK $PlayCDpatch
    DELETE >NIL: ENV:PlayCDpatch
ENDIF

Any help appreciated. I am sorry, I am not good at all with programming, even lame scripts!
