Purpose
Condition on repetition number.
Syntax

Description
This command can only be used inside a repetition block. It compares the current repetition with the number indicated by n. If these are equal the commands after the colon are executed. Optionally you can use the command *ELSE after which you place commands that are executed if the current repetition is not equal to n.
Arguments

Remarks
- The repetition number is stored in the system variable
