My only basic question is that :>: will :>: it be wise enough to code like below : :>: :>: SYMDEF(&SYSR2='MTSRS2') :>: SYMDEF(&SYSR3='MTSRS3').
If you code it like this, then when you have a second set of SYSRES volumes, say TSTRS1, TSTRS2, TSTRS3, &SYSR1 will resolve to TSTRS1 as you want but &SYSR2 will still resolve to the MTSRS2, not TSTRS2. :>: :>: I have referred the link :>: http://publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=%2Fco :>: m.ibm.zos.r12.ieae200%2Fplnsym.htm :>: but I am not really able to understand the below coding when we more :>: than :>: 1 sysres volumes : :>: :>: :SYSDEF . :>: :>: . :>: SYMDEF(&SYSR2='&SYSR1(1:3).RS2') /* second SYSRES logical :>: extension */ This code says set the value of &SYSR2 to the first three characters of &SYSR1 followed by the characters RS2. When you IPL from MTSRS1, the first three characters of &SYSRS1 are MTS so &SYSRS2 resolves to MTSRS2. And when you IPL from TSTRS1, the first three characters are TST so &SYSR2 will resolve to TSTRS2. This insures that &SYSRS1, &SYSRS2, and &SYSRS3 always resolve to the three volumes that are part of a matched set. :>: SYMDEF(&SYSR3='&SYSR1(1:3).RS3') /* third SYSRES logical :>: extension */" :>: :>: :>: Could anyone please explain me about the above syntax. How to make use :>: the of the above syntax reasonably. The only change you need to make to the above is to decide how many volumes are involved. My last system (1.11) had only two 3390-9s so I didn't bother with &SYSRS3. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
