Re: ALTER TABLE over multiple members

["Jim Franz" <franz400@xxxxxxxxxxxx>]

If your LF source is only a key definition, like
A          R ADPCR                     PFILE(ADPCUR)
A          K ADADPI

then the logical is changed along with the physical (you will see a rebuild
of the indexes
during the chgpf. One important note - a CHGPF to a physical (and all it's
indexes) does
not give the objects a new create date. If your change management software
is looking
only at "creates" to find new versions, these will not be found.

I'm in the middle of a large project merging multiple systems & companies
and we have used CHGPF to add fields, drop fields, expand existing fields to
hundreds
if not thousands of files (so many files is due to the old design) . Of all
that, only a very few, involving changing "attributes" of a field, like 5S 0
to 7A  have had to create conversion programs.
