Lexical operator for extracting elements from a list of elements.

    Format

      %ELEMENT  (integer,string1,string2)

1  –  Arguments

 integer

    The first argument, of type integer, is the element number to
    extract. The first element is number 0.

 string1

    The second argument, of type string, is the delimiter or
    delimiters that separate elements.

 string2

    The third argument, of type string, is the list of elements.

2  –  Description

    %ELEMENT is modeled after the OpenVMS DCL lexical function
    F$ELEMENT. It is used to extract one element from a string of
    elements. Note that unlike F$ELEMENT, you may specify multiple
    delimiters. The result is the specified string element. If the
    specified element number is greater than the number of elements
    in the list, the delimiter argument is returned.

3  –  Example

             .PRINT "%ELEMENT (2, <+-*/>, JOE+FRED-TOM*BILL/ERIC)"

      After lexical processing, the statement appears as:

             .PRINT "TOM"
