CoZBatch fopen error

[sedprm]

Can anyone help, getting a strange error trying to use CozSFTP 3.5.1 with a userid that hasn't used it before.

CoZBatchÝT¨: <- setupEnvironment()
CoZBatchÝT¨: -> openDDs()
CoZBatchÝE¨: ./CoZBatch.C(398) - fopen(//DD:STDIN,rt) - Ý21¨ EDC5021I The file attributes for open create an invalid combination. (errno2=0xC00B020F)
CoZBatchÝT¨: <- openDDs()
CoZBatchÝT¨: <- run()
CoZBatchÝW¨: an error occurred; returning rc=101

STDIN is defined as follows, nothing unusual about it, it's a PDS with RECFM=FB, LRECL=80, BLKSIZE=3200:

//STDIN DD DISP=SHR,DSN=SYSP.GB.COZ.SCOZPARM(SFTPIND)

[sedprm]

Replying to my own post, the problem was in the concatenation:

//STDIN DD DISP=SHR,DSN=&SFTPIND
// DD DDNAME=SFTPIN

The dataset that SFTPIN pointed to had inexplicably been created (not by myself I hasten to add!) with LRECL=91,BLKSIZE=27937. Recreating this dataset with LRECL=80 resolved the fopen error.

Good afternoon,
I have that same error message but what I find weird is that in the JCL where this step (STEP2) for removing a file fails, there's a previous step (STEP1) that gets that file to Mainframe and it works fine.
How can this be?

This is a problem where the IBM C library cannot open DD STDIN.

Check this DD in your JCL. If you have a concatenation, check that it is valid (the datasets use compatible RECFM/LRECL).
