Thanks a lot for all your support! Hi Steve - I'm now in Shanghai, China and yes I'm talking about zOS.
For your better understanding, I'm following the steps listed here: <http://www-03.ibm.com/servers/eserver/zseries/zos/sdsf/tools/sdsfrexx.html> in step 2, it says "Concatenate the panel data set to ISPPLIB and the skeleton data set to ISPSLIB." In my envrionment, ISPPLIB is allocated by a DD name in my logon procedure. So I think the context we are talking about is my user address space. When in ISPF, I can use command DDLIST to see the ISPPLIB ddname and several data sets in its concatenation, now I just want to add another one into them. The problem is I don't want to change the logon procedure - it is shared by many other users. Then I tried 'ALLOCATE F(ISPPLIB) DA('xxxxx') SHR' but still doesn't work. It seems that ALLOCATE will firstly deallocate the original ddname and then allocate again with the new data set. And it tells me that "FILE ISPPLIB NOT UNALLOCATED, DATA SET IS OPEN". So I just want to add a data set into the ISPPLIB concatenation while giving no influence on any other data sets already there. Hope that I've made my question clear ~ Thanks, Wei On Sun, Oct 11, 2009 at 8:50 PM, Steve Comstock <[email protected]> wrote: > bububut wrote: >> >> Hi All, >> >> I am new to Mainframe (get to learn Mainframe about 3 months ago).
