arraylength

Purpose

Count the number of values in a given variable.

Syntax

returnedNumber = arraylength(variableName)

returnedNumber - type: int
variableName - type: var

Returns

Remarks

Note that the variableName must evaluate to a variable reference (G, S, X, N).

WARNING: arraylength() never returns 0, since every variable is considered to have at least one value.  This may yield unexpected behaviors at times.
