> ISPF application environment. I'm not trying to set up an ISPF application environment.; I'm trying to set up a TSO user environment. I want to automatically activate user extensions to the standard conventions whenever the user has allocated libraries with appropriate names, e.g., userid,USER,EXEC, userid.USER.ISPP.
At other shops I've done it by reallocating the standard concatenations when the user libraries existed; I want an alternative to that. > ISPF works as designed NOVALUE is a REXX *style* issue and has nothing to do with ISPF. > everyone must follow these rules There is no rule in REXX requiring the use of SIGNAL ON NOVALUE. -- Shmuel (Seymour J.)

LIBDEF is commonly used to eliminate the need for reallocating standard ISPF DDs. There are situations where ISPxUSR is useful but I suspect most don't use it. I'm sure CBTTAPE.ORG has multiple examples of setting up the ISPF application environment. >Yes, typo for ISPxUSR. The allocation is before starting ISPF.

If you are developing an application, then I suggest avoiding ISPxUSR unless your requirements need it. Using LIBDEF for products means the datasets are freed when not in use. >I'm aware of the contingent that advocates NOVALUE, but I don't agree with >that perspective. ISPF works as designed and everyone must follow these rules or request they be changed. >To clarify, my logon panel calls userid.AD.CLIST, which does allocations, >ALTLIB and TSOLIB before calling ISPF. A requirement for products that I've worked on is that everything is contained within the REXX and nothing needs to be modified in TSO other than making the REXX available to the users who need it. > I want to add, e.g., user panels, in a form that will persist across START > (ISPSTRT). Persistence is typically achieved through REXX using the appropriate LIBDEFs. You would still need a REXX with permanent DD's because you should have a different ISPF ZAPPLID for your application. ---------------------------------------------------------------------- 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
