Examples

   1.$ SHOW LICENSE VMSCLUSTER*
     Active licenses on node NODE1:

     ------- Product ID -------- ---- Rating ----- -- Version --
     Product            Producer Units Avail Activ Version Release  Termination
     VMSCLUSTER         DEC          0  0     100    0.0  (none)    14-MAY-2005
     VMSCLUSTER-CLIENT  DEC          0  0     100    0.0  (none)    14-MAY-2005

     $ WRITE SYS$OUTPUT F$LICENSE("VMSCLUSTER")
     TRUE
     $ WRITE SYS$OUTPUT F$LICENSE("NONEXISTENT_PAK")
     FALSE

     In this example, the F$LICENSE function returns TRUE, which
     verifies that the VMSCLUSTER license is loaded on the system.
     In contrast, the status of hypothetical license NONEXISTENT_PAK
     is shown to be FALSE, indicating that it is not loaded on the
     system.

   2.$ WRITE SYS$OUTPUT F$LICENSE("ABC")
     FALSE
     $ WRITE SYS$OUTPUT F$LICENSE("ABC","XYZ")
     TRUE

     In the first instance, no license for product ABC is found from
     the default producer (DEC or VSI). In the second instance, an
     ABC PAK is found for producer XYZ.
