Hi JCLs,
1. Can we concatenate a PS?
2. ALTER can be used to Alter the LIMIT of the GDG for
a. sms datasets b. non sms c. both d. not in both.
3. Dummy datasets scope is beyond the Job. (t/f).
4. Release parameter releases the Primary allocated space only? (T/F).
5. Can Include group contain JCLLIB statement?
6. What is the use of a checkpoint?
7. In variable length records, the LRECL of JCL should be 4 less than that of cobol Record Length. |

1 yes any kind of dataset can be concatened :
//SYSLIB DD DSN=SYS1.COB2LIB,DISP=SHR
// DD DISP=SHR,DSN=****.ISPF.SISPLOAD
// DD DSN=****.PP.LINKLIB,DISP=SHR
// DD DSN=SYS1.LINKLIB,DISP=SHR
// DD DSN=SYS1.SCEELKED,DISP=SHR
one rule was the dataset with bigger blocksize on top but I believe it's been relieved with MVS SP4
2 c
3 NO scope is jobstep
4 here is release parm
//DD0 DD DSN=!!!.whatevr.JOBS,DISP=(MOD,DELETE),
// UNIT=SYSDA,SPACE=(TRK,(1,1,1),RLSE),LRECL=133,RECFM=FBA
and it does release PRIMARY space (T). |
