1) ALTERNATE KEY.
The COBOL standard (85 and 2002) only
allows one data item to be specified.
2) CRT.
As stated it is pending. It can only be implemented
when we have screen handling in place.
(On my TODO list)
Note this was not in the 85 standard (AFAIK), but is
in the 2002 standard.
3) LOCK MODE.
This was not in the 85 standard (AFAIK), but is in
the 2002 standard.
As stated pending.
For IS files, this is very much dependent on the
underlying software ie. Berkeley DB.
BDB does not provide the necessary hooks to
achieve this.
We may be able to do it if we eventually use
something else like VBISAM.
