VOLCT

The VOLCT keyword specifies the number of volumes that are defined to the data set.

Syntax

Read syntax diagramSkip visual syntax diagramVOLCT=( nnn,op)

VOLCT=(nnn,op)

Where:

nnn is an integer (1 - 255) that specifies the volume count.

Notes:
  • For preexisting data sets, the value is considered to be the number of unique prime and candidate volumes for both the index and data components of a cluster.
  • For DASD data sets, the maximum number of volumes is limited to 59. For tape data sets, the maximum number of volumes is limited to 255.
  • Do not use VOLCT for VSAM DEFINEs. VOLCT is valid for JCL or dynamically allocated data sets (including SMS and non-SMS VSAM and non-VSAM data sets). For IDCAMS DEFINEs use the NUMVOLS keyword instead.

Default
