Mainframe, MVS and zOS Discussion

If you do not understand and you use JCL then I suggest, strongly, that you read the JCL Reference manual as DISP has nothing to do with the program being executed..

[quote="Akatsukami"]The IDCAMS command is wrong; it should be DELETE FILE(ddname), hence the RC=8. If the disposition is (MOD,DELETE), the data set is deleted by the OS, not IDCAMS; if the disposition is OLD (which implies KEEP, KEEP), it is not deleted.[/quote]
Hmm .. now understood. Will DISP work like this for any program?

The IDCAMS command is wrong; it should be DELETE FILE(ddname), hence the RC=8. If the disposition is (MOD,DELETE), the data set is deleted by the OS, not IDCAMS; if the disposition is OLD (which implies KEEP, KEEP), it is not deleted.

//* 
//* STEP TO DELETE THE DATASET
//* 
//STP01 EXEC PGM=IDCAMS 
//SYSPRINT DD SYSOUT=* 
//FILE DD DSN=DELETE.THIS.DATASET,DISP=(MOD,DELETE) 
//SYSIN DD * 
DELETE FILE

Hi,

I try to delete a dataset, which exists, using IDCAMS. The JCL ends with RC 8.

[code]
//*
//* STEP TO DELETE THE DATASET
//*
//STP01 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//FILE DD DSN=DELETE.THIS.DATASET,DISP=(MOD,DELETE)
//SYSIN DD *
DELETE FILE
/* [/code]

Strangely the data set is deleting if the DISP=(MOD,DELETE) but the data set does not delete if the DISP=OLD. :sorry: But the return code for both of them is 8.
