How do I add and delete LNKLST datasets?

To replace a dataset in the LNKLST, you can do the following:

P LLA

SETPROG LNKLST,DEFINE,NAME=newlnklst,COPYFROM=CURRENT

SETPROG LNKLST,DELETE,NAME=newlnklst,DSNAME=old.dataset.name

SETPROG ADD,NAME=newlnklst,DSNAME=new.dataset.name,AFTER=dsname

SETPROG LNKLST,ACTIVATE,NAME=newlnklst

SETPROG LNKLST,UPDATE,JOBS=*

SETPROG LNKLST,DELETE,NAME=oldlnklst,DSNAME=old.dataset.name

SETPROG ADD,NAME=newlnklst,DSNAME=new.dataset.name,AFTER=dsname

SETPROG LNKLST,ACTIVATE,NAME=oldlnklst

SETPROG LNKLST,UPDATE,JOBS=*

S LLA,SUB=MSTR

You will need to allocate the new dataset before you can do this.

The last 4 SETPROG's is only needed if you want to run on the 'old' linklist name, it is purely cosmetic.
