Comments on Command Lines
You may annotate Qedit commands by putting comment text in curly braces at the end of the line:
keep sample,yes {update disc file}
Such comments are recognized at the “/” prompt, in usefiles, command files, and UDCs (of course, MPE won’t like them!), as well as Visual’s home line and Next? prompt and List’s More? prompt. In command files and UDCs the {comment} may appear on continuation lines, before or after the “&”.
