Cool.

Are there any obvious instances to be aware of where ALTER TABLE might fail ?

You can add a column in any place using ALTER TABLE, the option is "BEFORE fieldname"

Hi Richard

At least since V5R2, the CHGPF command lets you specify a source
member that has the changes, the data will be copied, changes made,
then data copied back - at least, that's the effect.

If DDL with SQL, ALTER TABLE gives some options - deleting, changing,
and adding columns can be done - adding has to be at the end, IIRC.

Cheers

What change are you doing?
Adding one or more new fields?
Changing an existing field - if so - from what to what
