Global storage GETBLK vector (X'000100030004')

The format of global storage GETBLK vector is shown in Table 1. One global storage GETBLK vector is built for each GETBLK subpool that exists in VTAM® per request for global storage usage data. A GETBLK subpool is identified by its pool ID and buffer size. A given GETBLK pool might also be made up of multiple subpools, each of which have a different buffer size.
