Task Sequence variables and batch file

hi all experts,

just wondering if there is an easy way to pass on the TS variables into a batch file. I have a working Run Command Line step on my TS as follows:

cmd.exe /c "set tsname=%_SMSTSPackageName% & .\mybatchfile.bat"

This is ok when only passing on 1 variable, but not with many variables as you can imagine. '

Any idea of any other way that fits in with multiple variables scenario?

Thanks,
Xm
