Re: [GnuCOBOL-users] select same file twice?

[Ron Norman]

Adding a new file to parallel BDB and hold file information (record size, keys etc) would be useful.

But much less important/urgent than getting the rest of reportwriter merged into trunk.

Yes, that was what the test. But as the test is called "EXTFH: using
ISAM callback" that is really hard to catch.

We should adjust the test, at least adding a COBOL comment there and
extend AT_KEYWORDS to include the tested status 39.

As we handle this for BDB it should not be ignored (and for LMDB work
identical if there's no "record size concept" there).
For BDB/LMDB we should add a (possibly optional) data dictionary, if
possible included (I think to remember there was an option to add
textual metadata to a BDB file), otherwise as a separate file (like
".dd") to allow full support for not specified ALTERNATE KEYs,
everything that is record specific, ...
I'm fine to have this postponed until rw-branch is fully merged.
