Thanks to the replies

[TAO%OPUS at mcoiarc.bitnet]

My sincere thanks to everyone who replied to my request for help on PIR.

I have successfully retrieved the sequences I needed by sending e-mail

commond to FILESERV at GUNBRF.BITNET.  The best way to start with is to send

the command HELP to this address.  However, anyone may find it otherwise.

A side story is that the e-mail protein sequence search against PIR database

is free and very fast (maybe this is because of the fact that I was doing it

over the weekend?).
