YES (or Y)
(YES,-mmm,+nnn)
Prints the DISTRIBUTION OF ROOT SEGMENTS part. Y can be used as a shortened form for YES.

mmm is the backward distance from the home block (1-999) and nnn is the forward distance from the home block (1-999). Plus sign (+) can be omitted.

If only YES is specified, the range is assumed as -10 to +10. The randomizer module is used for this option. Specify the data set name that contains the randomizer module on the STEPLIB DD statement.

If a segment edit/compression exit routine is defined for a root segment, the segment edit/compression exit module is used for this option. Specify the name of the data set that contains the segment edit/compression exit on the STEPLIB DD statement.

NO (or N)
Does not print the DISTRIBUTION OF ROOT SEGMENTS part. N can be used as a shortened form for NO.
