Hi,
I am just in despair.
I have a job in a job chain that sorts a previously created file. This file is then processed by various subsequent jobs.

Now the just created SORTOUT is deleted by SORT as soon as the input file does not contain any records. So the subsequent jobs abort. What can I do so that the empty SORTOUT is not deleted.

By the way, the job has run without problems for the last 20 years and has always created an empty SORTOUT if the SORTIN did not contain any records.

I attach the respective job step.

Code:
//STEP030  EXEC PROC=PGMLOAD,DBID=31,PROG=SORT                 
//SYSOUT   DD SYSOUT=*                                         
//SORTIN   DD DSN=infile,DISP=(OLD,DELETE,KEEP)   
//SORTOUT  DD DSN=outfile,DISP=(NEW,CATLG,DELETE),     
//            DCB=(LRECL=32095,RECFM=VB),                       
//            SPACE=(CYL,(20,40),RLSE)                         
 SORT FIELDS=(9,3,A,30,6,A,36,26,A,62,48,A,113,4,A),FORMAT=CH   
 RECORD TYPE=V,LENGTH=32095

What is the JCL in the PGMLOAD procedure?

Garry.

A Cobol program that creates a list, but the list can be empty.

Code:

//MBSPRO   DD SYSOUT=*                                                 
//QUELL2   DD DSN=input1,DISP=SHR     
//PROTOK   DD DSN=protdat,DISP=(MOD,KEEP)             
//WORKFILE DD DSN=infile,

Show the resolved PROC and also add the //SYSIN DD to the stream (it's missing).

And also: include the part of SDSF log showing the point where your SORTOUT has been deleted!

One stupid question: where your abstract "DSN=infile" and "DSN=outfile" come from?
There is a chance that after "too smart" parameter substitution you are using the same name in both DSNAMEs?


P.S.
It is a very-very-very bad idea: asking abstract questions without giving any specific detail.
It is the same as the question: "I did everything right, but the result was wrong. Please, help!"

Sorry for being so straightforward, but this reminds me ravings of lunatic: using THE SAME JCL PROC, while running ABSOLUTELY DIFFERENT PROGRAMS!!??

Such way of coding is the basic origin for "mysterious disappearing of datasets", and other "miracles".

To say nothing about the fact, that SORT has no physical ability to "delete datasets" (according to the Topic name).

Can we assume that the blank in front of
//STEP030 EXEC PROC=PGMLOAD,DBID=31,PROG=SORT
is a cut/paste error? If not then you essentially only have one step.
Like Segeyken I wonder what really is in that PGMLOAD proc since you seem to override most JCL.

And I too would like to see the SDSF listing.
