Hi All,

I have created a ISPF Table using TBCREATE for 3 fileds. Now we have a requirement to add a new filed.

My question is can we add a new field to existing table?

Thanks.

From STFW:

When you want to expand the table by adding columns, you have to
modify the TBCREATE statement and several other ISPF services dealing
with this table. This means that you have to recreate the table itself
in a new structure.
Thus may lead to further problems as it might be very important to
preserve the data already stored in the table. In this case you should
think about a migration routine.
