Perhaps it's too obvious, but the z/OS release level provides certain information. Specifically:
1. If you're on z/OS 1.6 or a higher 1.x release, you know you're on a z900/z800 or higher and cannot be on a 31-bit machine. 2. If you're on z/OS 2.1, you know you're on a z9 or higher. 3. If you're on z/OS 2.2, you know you're on z10 or higher. 4. If you're on a future release of z/OS higher than 2.2, it's reasonable to assume you're on z10 or higher. This'd be a first level check, and then you can cautiously "upgrade" the machine level determination from there. This'd be appropriate, base level analysis for zPDT and RDTz environments, for example. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA -------------------------------------------------------------------------------------------------------- E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
