Think of the OMVS command as doing a fork() to start a new UNIX process. Which is what it does. But the "oedit" command is just a communications tool to send a file name back to the "parent" process (ISPF) telling it to do an ISPF edit on the given UNIX file. The "oedit" command then "waits" for the ISPF process to tell it to resume. So the editing is actually being done in the user's TSO address space. That's why you can SWAP to another ISPF screen while doing an "oedit". The UNIX / OMVS process is asleep during this time. To me, this is conceptually similar to running a stored procedure in some data bases. The user requests the stored procedure, but it runs using the UNIX identity of the RDBMS server, not the user. At least, that's what somebody told me. I don't remember which RDBMS they were talking about. > -- gil > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN > -- Computer Science is the only discipline in which we view adding a new wing to a building as being maintenance -- Jim Horning Schrodinger's backup: The condition of any backup is unknown until a restore is attempted.
