Adding comments to a formula
For complex or infrequently used formulas, you can add comments to explain the details. Use block comments or end-of-line comments, which you can enter anywhere in a formula.
Block comments start with the characters /* and finish with the first occurrence of the characters */. Your explanatory text appears between the two asterisk characters. Comments can begin on one line and end several lines later. You can nest block comments.
End-of-line comments begin with the characters // and finish at the end of the line.
To add comments to a formula:
- In the Specify Calculation dialog box, enter your comments.
See Defining calculation fields for information about the dialog box.
- Click OK.
