How do I assign the output of command to a macro

[swhite]

I am executing git describe with the following command-line options.
--match v_*

this outputs the value i want, but i can't figure out how to assign that value to a Macro, I need to parse that output in a VBScript task.

Thanks

See the vbld_StepDone script event and LASTSTEP_OUTPUT system macro.
