    |     | I saw the messages about using locks when interacting with the screen.  Could
    |     | someone provide a short snippet of code showing how one would use those 
    |     | unexported clim calls initial-lock-values and with-lockf?
    | 
    |     I wrote the question to which locks were the answer.  I had the same
    |     problem you do.  Instead of using Clim locks, I used the locks in
    |     Allegro's multi-processing system.  Since you have a multi-process
    |     application, your lisp must have some sort of lock mechanism.  My code
    |     is very simple.   ...
    | 
    | This doesn't do you any good for CLIM 1.0/1.1, but you should use
    | CLIM-SYS:MAKE-LOCK and CLIM-SYS:WITH-LOCK-HELD in CLIM 2.0, since
    | they are portable across all platforms that implement CLIM.

My suggestion doesn't do you any good for CLIM 1.0/1.1

    1) Since it protects the processes from accessing the screen
    simultaneously, why doesn't it do me any good?

    2) I'm using CLIM 1.1, and I still don't know what calls to use.  I
    can't find any documentation in the CLIM 1.0 manual, the only one I
    have.  What are they?
