I can see that the main stumbling block in the use of DELTA programs is
the preparation of input files (CHARS, ITEMS, SPECS, etc.). To prepare
these files is a painful process, almost as complicated as solving the
RUBIK CUBE. If you make a small change in CHARS file (add or delete a
character), you have to make endless changes in the ITEMS file and other
If you are interested in an interactive identification program, I would
recommend using XID system developed and distributed by
XID Services, Inc.
Post Office Box 272

XID system has an extremely user-friendly "menus" for entering,
changing, and editing characters and items. You can enter the data in a
fraction of time it would take you to create CHARS, ITEMS, SPECS etc.
I have not had chance to compare performance of XID and INTKEY, but
I don't think one will be significantly better than the other.
One thing DELTA definitively needs is an easier method of how to enter
taxonomical data. XID input method proved that it can be done. Can DELTA
people approach the XID Services, and ask them to provide an interface
between XID input and DELTA input? Both XID and DELTA would benefit from
such a marriage.
