    Format

      %LENGTH  (string)

1  –  Argument

 string

    The single argument, of type string, is the string from which the
    length is to be computed.

2  –  Description

    %LENGTH is modeled after VAX MACRO's %LENGTH macro string
    operator and the OpenVMS DCL lexical function F$LENGTH. %LENGTH
    is used to determine the length of a string. The result is the
    length of the string expressed as a decimal number.

3  –  Example

             .PRINT "%LENGTH(<The quick brown fox>)"

      After lexical processing, the statement appears as:

             .PRINT "19"
