Function

The SET TIME (or SETTIME) statement is used in conjunction with the Natural system variable *TIMD to measure the time it takes to execute a specific section of a program.

The SET TIME statement is placed at a specific position in the program, and *TIMD will contain the amount of time elapsed since the execution of the SET TIME statement.

*TIMD must always contain a reference to the SET TIME statement, either by using the source-code line number of the SET TIME statement or by assigning a label to the SET TIME statement, which can then be used as a reference.

Example

** Example 'STIEX1': SETTIME
