## SET TIME Usage

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.

## SET TIME Example

    ** Example 'STIEX1': SETTIME
    ************************************************************************
    DEFINE DATA LOCAL
    1 EMPLOY-VIEW VIEW OF EMPLOYEES
      2 NAME
    END-DEFINE
    *
    ST. SETTIME
    WRITE 10X 'START TIME:' *TIME
    *
    READ (100) EMPLOY-VIEW BY NAME
    END-READ
    *
    WRITE NOTITLE 10X 'END TIME:  ' *TIME
    WRITE         10X 'ELAPSED TIME TO READ 100 RECORDS'
                      '(HH:MM:SS.T) :' *TIMD (ST.) (EM=99:99:99'.'9)
    *
    END

#### Output of Program STIEX1:

    START TIME: 16:39:07.6
    END TIME:   16:39:07.7
    ELAPSED TIME TO READ 100 RECORDS (HH:MM:SS.T) : 00:00:00.1
