The program continues to prompt for a second segment. If you put
-default on the command line the program will stop after the first segment.

This is normal, and was even the case under VMS because GCG does not
use the standard DCL command line parsing. Of course once you put
-default on the command line the program asks no questions and you
always have to check the output carefully to be sure the command
line was correct.

Not to sure what you want here, but perhaps the problem is that FINDPATTERNS
always writes 5 residues before and after the hit. This, for some reason,
is hardcoded into GenApplib:showhits.f
You could work around this by extending the pattern with the required number
of X positions. These will match anything, and will be reported as part of
the hit.
One problem with this approach is that you will miss any hits that do
not have enough flanking residues, but you can catch those by running without
the Xs.
Perhaps a future version will let you specify the extra 5 residues before and
after the hits on the command line - quite easily done by a change to
the showhits function.
