>>-ISREDIT--(var1,var2,var3)-- = --VOLUME----------------------><

var1: The name of a variable to contain the serial number of the volume on which the data set resides. For a multivolume data set, this will be the serial number of the first volume. The volume serial number is a six character value.
var2: The name of a variable to contain the number of volumes the data set occupies. The number of volumes is a two-character value.
var3: The name of a variable to contain the serial number of the volume of the original data set.

0: Normal completion
4: The data set is a multivolume data set and the shared pool variable ZEDMVOL is set to contain all the volume serial numbers of the data set. ZEDMVOL has the length of the number of volumes times six.
20: Severe error

To retrieve just the volume serial number of the data set:

ISREDIT (VOL) = VOLUME

To retrieve just the number of volumes the data set occupies:

ISREDIT (,NUMVOL) = VOLUME

To retrieve both the volume serial number and the number of volumes the data set occupies:

ISREDIT (VOL,NUMVOL) = VOLUME
