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 'STIEX1': SETTIME
