SSIS 2008 - How to capture multiple output variable values from Execute Process Task

Hi,

I am using a Process Task  in SSIS 2008 inside a ForEachLoop container to unzip a file into 2 csv files, and I want to check that the file creation timestamps on the 2 csv files are for the same day, and exit the package without triggering an error if they are not.

I am trying to capture the 2 csv filenames into variable values from the output of the Process Task, but not sure how to do this using the ExecValueVariable property on the Process Task. The 2nd variable will overwrite the first - what datatype should I use for the variable?

or is there a better way of achieving this?

thanks.
