IDLETRKS — Idle tracks (number)

For all processing of non-VSAM data sets, and reporting on VSAM components with "SCAN REALVOLS, REPORT COMPONENTS", the value of IDLETRKS is set to the total number of tracks occupied by the data set or component as shown by its Format-1 and possible Format-3 DSCBs, less the value of the DS1LSTAR field in the Format-1 DSCB for each data set or component.

For all other processing of VSAM clusters, the value of IDLETRKS is set to the number of tracks represented by the difference between the High Allocated RBA field HARBAS and the High Used RBA HURBAS in each cluster's catalog entry.

Note: Do not use this parameter for PDSEs in ESA 4.3 or higher environments because their DS1LSTAR is always zero.
