> Or imagine my astonished dismay the first time I allocated a member with DISP=(OLD,DELETE) and watched the entire PDS vanish.
In the early 1970s, at a bank using MVT on 370/155, soon after DOS-OS conversion, all procs were stored in SYS1.PROCLIB. Excessively neat programmer deleted a member using that technique. System was unbootable. When the system came back after the sysgen (no backup res pack!), an APPL.PROCLIB was created and all SYS1 datasets were password protected. Ops was not given the password. So in 40 yrs, the same design flaw has bit how many people/shops? On the other hand, most programs I wrote in the 1960s would run today, if there were still card readers. ----------------------------------------- The information contained in this communication (including any attachments hereto) is confidential and is intended solely for the personal and confidential use of the individual or entity to whom it is addressed.
