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
