Supposing the PDS's name is 'THISIS.ANAME', doing:
| Code: |
address TSO
"ALLOC DD(TEST) DSN('THISIS.ANAME(NEWMEMBR)') SHR"
|
This will allocate a new member in the PDS, or overwrite an existing one.
If you prefer to append to the member instead of overwriting it, use MOD disposition instead of SHR. |

Nope, you can't ever MOD to a member of a PDS. It's either SHR or OLD. |

And here is the quote from the fine manual:
| Quote: | | Do not use the MOD attribute when allocating a member of a PDS to which you want to append information. You can use MOD only when appending information to a sequential data set. To append information to a member of a PDS, rewrite the member with the additional records added. |

address TSO
"ALLOC DD(TEST) DSN('THISIS.ANAME(NEWMEMBR)') SHR"
If i am replacing the member name by a temp variables(i.e. putting any variables let say VAR1 in place of the 'THISIS.ANAME(NEWMEMBR)), then i am getting RC = 12 . why i am geting RC=12 ,Can we use variable which have the member name for allocating? |

Could you post the results of your TRACE of the ALLOC step? Something to check for - make sure there are no imbedded blanks in either the dataset or member name.
If VAR1 is 'NEWMEMBR', then you can allocate the DD as:
| Code: |
"ALLOC DD(TEST) DSN('THISIS.ANAME("VAR1")') SHR"
|
