ISPF table is a very generic term,
which table You want to update?
I do not see any use in adding fields,
ISPF will never use them,
furthermore ISPF might change it' s internal tables layout
be a little more specific on what You want to do

I presume that Mustafa is asking about a specific user-defined table.
Off the top of my head, I would imagine the process to be
- TBOPEN the existing table.
- use TBQUERY to determine the existing index and field names.
- use a loop with TBGET to retrieve each table row, storing the data as either REXX stem variables or into a temporary dataset.
- TBCLOSE the existing table.
- TBCREATE the new table, with the old table's name, indexes and fields, with the new field added.
- TBADD the rows to the new table.
- TBCLOSE the new table. |

Hi superk!
what bothers me in this kind of question is that the poster does not give anybody the slightest idea that he tried to help himself before asking...
I know I was being picky, in my remark, but given your assumption, reading the application which manages the user table should have given him a little hint on how to proceed and ask a question more apt to get help
If I were a founding father I would require that all the posters should declare, before posting, to have read and understood the following howto

Most of the ISPF table-services which allow a table update (like TBADD, TBMOD, TBPUT) allow the use of extension variables. Please refer to the fine manual for more information.
