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.
Example of block comment
Everything shown below can be entered inside a formula:
/* This is a calculation with block comments nested and multiline comments
/*----- It returns the title if it exists in a name -----*/
*/
Case (
PatternCount( "MrMsMrs", LeftWords( Name, 1 ) ), /* returns true if the first word in fieldName matches anyone of the titles Mr, Ms or Mrs */
LeftWords ( Name, 1 ) /* extracts the title */
)
Example of end-of-line comment
Greeting & "!!" // returns Hello!! if field Greeting contains the string "Hello"
