Hi all,

How to override a concatenated dataset??

Generally we give stepname.ddname, but the concatenated datasets share same ddname. What dd name should i use??

How many datasets are concatenated in the DDname. Say for example you have 2 datasets already concatenated to the DDname and you want to override the 2nd dataset concatenated then use this.

Code:
//STEPNME.DDNAME DD
//               DD DSN=HLQ.ABC,DISP=SHR

And beware the use of DD DUMMY.

The first one encountered will end the concatenation string.
