We use 24x7 to generate user datafiles. The users dial into a special PC
to retrieve their files. We have a requirement now to encrypt these files
before the users pick them up. Are you aware of any encrytion packages that
may be run from 24x7 scripts? All of the ones I've looked at need to be run
from the Windows GUI. Thanks.

Take a look at PGP. PGP is a freely-redistributable public key cryptosystem for MS-DOS, Windows, UNIX and other systems.
