# $EPIC: numarrays,v 1.2 2001/06/22 20:01:37 jnelson Exp $
Synopsis:
   $numarrays()

Technical:
   This function shows the total number of arrays created by $setitem().
   It takes no arguments, and ignores any passed to it.

Practical:
   This function is used to show how many arrays currently exist.  This
   might be useful if the arrays were named in a sequential order, thus
   allowing you to know what the next available number is.

Returns:
   > 0   number of current arrays
     0   no arrays found

See Also:
   Arrays(7); getarrays(6); setitem(6)
