Yep. ask why he needed it, and make him reconsider FTPG: I personally do not recall one situation where I exploited this information and did not regret it later ;-) One of the "smart" examples is VMLINK that hides messages when I invoke it from inside a dumpscan macro. Very inconvenient when the macro produces output in line mode and you get the VMLINK messages out-of-order depending on the number of messages. The Linux shell uses similar things to have programs produce different output depending on whether stdout is redirected (like display data column-wise). I am not sure that is the right approach. But leaving the choice to the "shell" means no program can be smarter than the API that the shell provides. Rob
