Are for Comments or Indentation
Qedit commands can have comments attached to them, as long as they are enclosed in curly braces:
/keep justify.stream,yes {update disc file}
Qedit recognizes these comments at the “/” prompt, in usefiles, command files, and, although MPE won’t like them, in UDCs. Qedit also accepts comments on the home line in Visual mode, and at the More? prompt in Browse mode. In command files and UDCs, you can place your {comment} on continuation lines, before or after the ampersand (&).
STREAMX Warning: Don’t use these {comments} in job streams if you use STREAMX from VESOFT because it interprets them as parameters to be substituted.
Braces are also used in the Add Justified and Replace Justified commands to indicate a change of indentation.
