ALLOSEC — Secondary allocation amount (number)

For all processing of non-VSAM data sets, and reporting on VSAM components with SCAN REALVOLS, REPORT COMPONENTS, the value of ALLOSEC is set to the secondary allocation amount (like the 1 in SPACE=(TRKS,(2,1)) as determined by the Format-1 DSCB for each data set or component.

For all other processing of VSAM clusters, the value of ALLOSEC is set to the secondary space allocation (like the 1 in TRACKS (2,1)) field SCONSPAC in the catalog entry for each cluster.
