Re: Cannot Add a logical file member. Not sure why

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Pete,

The "File Level Identifier" changes any time you create the file and
the "Member level identifier" changes when you create a member. But
neither one of those cause level checks.

"Format Level Identifier" is the one you need be concerned about.  It
changes whenever the record format changes.
- add/remove fields
- change types or sizes of fields
- change the short system name of a field or the record format name
- change other attributes of the field, CCSID, ALWNULL, DEFAULT...

Basically, any attribute of the field or record format that effects
how the data is seen/handled by the system.  In fact, the "format
level identifier" is basically a hash of those various attributes.

So for example, you can change the COLHDG or TEXT of a field without
changing the "Format Level Identifier" and thus without causing a
level check.

HTH,
Charles
