Crystal Reports for Rational Application Developer Designer Guide

Formula comments are notes included with a formula to explain its design and operation. Comments do not print and they do not affect the formula, but they appear on the Formulas page. You can use comments to explain the purpose of a formula or explain the steps involved in writing it.

Comments begin with two forward slashes (//) and are followed by the text of the comment. Everything that follows the slashes on the same line is treated as being part of the comment:

//This formula returns the string "Hello"
//This is another comment
"Hello" //Comments can be added at the end of a line
//Comments can occur after the formula text
