Indicator-Setting Operations

The indicator setting operation codes are:

• SETOFF (Set Indicator Off)
• SETON (Set Indicator On)

These operation codes are available only in the traditional syntax. In free-form syntax, you can set the value of *INxx to *ON or *OFF using the EVAL operation.

The following indicator-setting built-in function is available in both the traditional syntax and free-form syntax:

• %NULLIND (Query or Set Null Indicator)

The SETON and SETOFF operations set (on or off) indicators specified in positions 71 through 76. At least one resulting indicator must be specified in these positions. Remember the following when setting indicators:

• The 1P, MR, KA through KN, and KP through KY indicators cannot be set on by the SETON operation.
• The 1P and MR indicators cannot be set off by the SETOFF operation.
• Setting L1 through L9 on or off with a SETON or SETOFF operation does not set any lower control level indicators.
