How to call global variable in Run Program component

Hi,

I am using the Run Program (On Server) component for running some of the commands instead of using the command prompt directly, so I am providing some path in the command line and the path contains the global variable which is globally defined in the previous components but when I am running the protocol it gives me an error "unexpected token : @Global variable". Do anyone know how can we call a global variable in the command line.

Thanks in advance!
