No, IBM numbers bits from the left. In an 8-bit field, bit 0 corresponds to a mask of '80'x and bit 7 to a maskm of '01'x.

Bit 0 is usually the X'01' bit in mainframe doc (other than UNIX). So is my interpretation correct? SMF30_USERKEYCSAUSAGE is x'02'? Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Charles Mills Sent: Monday, April 18, 2022 8:33 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Trying to understand SMF30_RAXFLAGS We have a client who is trying to report on user key CSA usage. He is having trouble understanding the IBM doc, as am I. The SMF doc I am familiar with documents bits as X'80', X'40', etc. But the SMF30_RAXFLAGS doc (both the APAR and the new manual) documents the bits as Bit 0, Bit 1, etc. Usually in mainframe documentation "bit 0" refers to the x'80' bit. But what the client is seeing is values for SMF30_RAXFLAGS of binary 1, 2 or 3. Can anyone confirm my interpretation of what he is seeing that by "bit 0" IBM means X'01', by "bit 1" they mean x'02', and so forth? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
