# Description

As reported in https://github.com/isaac-sim/IsaacLab/pull/3071, we have
some issues with the isaaclab.bat script when multiple calls to
`!python_exe!` are called, resulting in ` '!python_exe!' is not
recognized as an internal or external command` error messages. This fix
uses `call` command to expand `!python_exe!` to and correctly execute
the commands.
