hi,
i use IEFBR14 in JCL to create PS dataset and PDS dataset,but how to create a member for existing PDS dataset? how to set the DISP or other parameters?
Thanks a lot!

You have to actually write something, so you need a real program - SORT, IEBGENER, IEBUPDTE, whatever you feel like using.

As MrSpock says, you have to use a program that will write some data into the PDS, for example -

Select all

//INITPDS EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT2 DD DSN=newpds(member),...
//SYSUT1 DD *
Data for a new PDS member
/*

JCL like this will allocate the PDS, but it won't write anything to it.

Select all

//ALLOCPDS EXEC PGM=IEFBR14
//NEWPDS DD DISP=(NEW,CATLG),DSN=pdsname(member),...

MrSpock gave a list of "standard" programs you can use, though there are many more programs, including programs that you write or have already written.

And remember, DISP is for the data set, NOT for the member.
