I can't see any mention of the uppercase -D flag in the documentation for Columns in CDPR7.
Can you tell us where you have seen this?
Perhaps more to the point is that there are tools in both Soundloom & Soundshaper that might work for you.
From the Columns html help -
COLUMNS is fully implemented in the Sound Loom GUI as the 'TABLE EDITOR'. In Soundshaper it can be found under the 'DATA > Data Editor' menu items (a file with columns in it, such as a breakpoint file, needs to be Opened before the menu items will be active). There is excellent documentation in Soundshaper on the Data Editor (which includes the functions in SNDINFO UNITS) in 'Help > Soundshaper Help > DATA EDITOR'.
