After the MSFN guide on OEMs

<<You might ask, "why not run application installations from the CD itself?" This is because CD-ROM drive letters are bound to be different on every PC, which shows why there's no permanent "%CDROM%" environment variable.>>

I don't know if I can use other windows system variables:

Help Appreciated

why not use a variable to set cdrom

example

for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\win51 set CDROM=%%i:

since win51 should be in the root of you cd it will set cdrom to the right drive letter then you could run the program by using

%cdrom%\path\program.exe

Thx, but that's not perfectly what I'm looking for... If I want just copy files like that I'm obliged to do a batch, can't I use the variables??
