I'm writing a Physical File System (PFS) for USS, and I've come across an oddity in the interface documentation. The "Environment for PFS Operations" section of z/OS UNIX System Services File System Interface Reference says that, on entry to VFS function routines, R13 is "Save area address, of a 136-byte save area". I don't think there is such a beast. I'm guessing it means that I should treat this as a 144-byte F4SA, and not chain forward (using the "next" slot at +136 of the old save area).
Has anyone else used this interface, and if so, can you confirm that this is how it's supposed to work? This is supervisor-state, key-zero code, some I'm eager to get it right the first time. :-) Thanks! -- Jerry ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
