Input redirection for DESCRIBE is no longer working correctly in TCC 17. Here's a line that I use in numerous BTM and REXX scripts: *DESCRIBE TargetFile <TmpFile If TargetFile already has a description, that command in TCC 17 appends the redirected description to the existing one. In all previous versions of TCC the existing description would be replaced. By previous versions I mean from TCC 16 back to the early days of Windows XP. Update: I just checked my archives and the earliest version of my cpdesc script that I still have was in 1999.
