The formula editor in SAS Activity-Based Management 7.1 and 7.2 supports both single-line and multi-line comments. This makes it possible to embed explanations and document changes in attribute formulas, driver formulas, and driver rule formulas:

• to mark a single line of text as a comment, precede it with the characters //
• to mark multiple lines of text as a note, precede the first line with the characters /* and follow the last line with the characters */
  The following example is a driver rule formula preceded by a single-line comment and followed by a multi-line comment.

   //This is a single-line comment that the formula parser will ignore.
