'''F$LICENSE''' is a [[Lexical functions|lexical function]] that checks whether the specified [[Licensing|license]] is loaded on the system (valid for [[Alpha]] and [[Integrity]] server systems only).

=Syntax=

F$LICENSE(license-name[,producer-name])

=Return Value=

A character string stating TRUE or FALSE.

=Arguments=

==license-name==

Specifies the name of the license for which you want to check the status.

==producer-name==

Specifies the name of the company that produced the license. By default, DEC is assumed to be the producer on Alpha systems and VSI is assumed to be the producer on Integrity server systems. To find an exception, specify a different producer name.

=Examples=

<nowiki>
$ 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
</nowiki>

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.

$ 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.
