[Bug-XBoard] chess-formula

[venko ganev]

Hello you! I registered in the freechess.org.
 I am interested in how to create a formula whereby using the command
"seek" not I invite users with a rating lower than 1600 as my score is
over 1600. I would be very grateful if I describe in detail the
creation of such a formula as leading to the auxiliary fail something
not working, perhaps I can not figure it out. Use winboard 4.5.2 jaws
if it matters. Thank you!
