Syntax

getLength( )
  RETURNS INTEGER

Usage

The getLength() method returns the number of elements in the array represented by this reflect.Value object.

Example

IMPORT reflect
MAIN
    DEFINE arr DYNAMIC ARRAY OF STRING
    DEFINE val reflect.Value
    LET arr[1] = "aaaaa"
    LET arr[2] = "bbbbb"
    LET val = reflect.Value.valueOf( arr )
    DISPLAY "len = ", val.getLength()
END MAIN

Shows:

len =           2
