/* FL module -- interface to Mark Overmars' FORMS Library. */

/* This code works with FORMS version 2.2 (if you defined
   OBSOLETE_FORMS_CALLS), and 2.3.
   FORMS can be ftp'ed from ftp.cs.ruu.nl (131.211.80.17), directory

/* A half-hearted attempt has been made to allow programs using this
 * module to exploit parallelism (through the threads module). No provisions
 * have been made for multiple threads to use this module at the same time,
 * though. So, a program with a forms thread and a non-forms thread will work
 * fine but a program with two threads using forms will probably crash (unless
 * the program takes precaution to ensure that only one thread can be in
 * this module at any time). This will have to be fixed some time.
 * (A fix will probably also have to synchronise with the gl module).
