  Name:     nlen() - get the length of any variable type
  Usage:    <integer> = nlen(memvar)
  Params:   variable to get the length of
  Returns:  length of that variable regardless of it's type

 ---------------------------------- Example ---------------------------------

                 m1 = "FUNCKy library"
                 ? nlen(m1)          && prints 14

                 m2 = 13.4365
                 ? nlen(m2)          && prints 15

                 m3 = date()
                 ? nlen(m3)          && prints 8

            With nlen() there is no need to convert the variable
            to type char.
