 |
|
hi all,
we can use LASTCC or MAXCC in Control information with IF or SET in IDCAMS.
But, can anyone please help me out in having exact distinction between these two.
Thanx in advance.

Pzmohanty,
LASTCC is set by the processor at the completion of each functional command (Repro, Define cluster...).
MAXCC is the highest value of LASTCC thus far encountered.
Hope this helps...
Cheers
Kolusu

hi Kolusu,
Thanks for the prompt reply ...........
But can u please make the things more clearer.
are the LASTCC or MAXCC only linked with return codes with in the same IDCAMS Control Card.
if my step previous to IDCAMS is anything other than IDCAMS , then also can i use LASTCC or MAXCC in IDCAMS step to control the previous return code ( i.e RETURN CODE of previous step).
Thanx.......

No they can be in different steps
| Code: |
//STEP0100 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE 'AN NON EXISTING DATASET'
/*
//STEP0200 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//FILE01 DD DSN=AN EXISTING DATASET WITH ATLEAST 1 RECORD,
// DISP=SHR
//SYSIN DD *
PRINT INFILE(FILE01) CHARACTER COUNT(1)
IF LASTCC = 4 THEN DELETE 'USELESS DATASET'
/*
|
In the above job, the first step ends with a return code of 8 since the dataset is not present.
In step0200 we first print 1 record and if the file is empty , then we issue another command to delete some useless dataset
Now the maxcc of the job is 8 whereas the lastcc of the job is 0

Sure you can
| Code: |
//STEP0100 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE 'AN NON EXISTING DATASET'
/*
//STEP0200 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//FILE01 DD DSN=AN EXISTING DATASET WITH ATLEAST 1 RECORD,
// DISP=SHR
//SYSIN DD *
IF LASTCC = 4 THEN DELETE 'USELESS DATASET'
/*

Hope this helps...
