Mark,
I have several hundred lines in my command window right now and the only rows that show up as comments (yellow on black for me) are bonafide comment lines.
What happens if you copy _command.prg to another file and then MODI COMM that prg does show the same thing?
>i have noticeed in the last week that when i scroll up through my command window some of the commands are in green. there does not seem to be a connection between any of them, some browse commands but not all, some modi form commands but again not all etc. i have comments set to show in green but none of these commands are commented out.
