Thanks, Tony, the SMF option I tried, unfortunately the records for open/close of USS files are not written in all cases.
Don, the service stubs are loaded at USS startup and reside always at the same offset like published in the document you pointed out. I.E. BPX1OPN -> 156 Thats the way you can find it with Assembler. But it is possible to call them or even the BPX4xxx (64 bit) straight from the CSSLIB? I'm not completely sure about it. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
