I would just do an EXECUTE to a scripting language and parse the results. An ls -l with some awk will make quick work of it. Here is a thread that describes ways to do it in python. http://stackoverflow.com/questions/237079/how-to-get-file-creation-modification-date-times-in-python PCPERFORM \python -c "import os; print os.stat('test.xml').st_mtime"\ CAPTURING OUTPUT will come back with the modification time in epoch time. _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
