Part of longstring preceding character in delimiter set

Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Lstr_Parse function is the Before function; also see the StringTokenizer class.

This function returns part of a given string: the characters after a specified or implied starting position and until a character in a delimiter set.

The $Lstr_Parse function accepts three arguments and returns a string result that is a part of the first input string.

The first argument is an arbitrary string or longstring.

The second argument is a string containing a set of delimiter characters.

The third argument is a starting position in the first argument string and has a default of 1.

Syntax

%PIECE = $Lstr_Parse(string, delims, [start_pos])

%PIECE is a piece of the first argument string.

For example, the following statement would set %JUNK to WASTE NOT:

%JUNK = $Lstr_Parse('WASTE NOT(WANT|NOT', '(|')

The statement below would set %JUNK to WASTE NOT(WANT:

%JUNK = $Lstr_Parse('WASTE NOT(WANT|NOT', '|')

The following statement would set %JUNK to E NOT(WANT:

%JUNK = $Lstr_Parse('WASTE NOT(WANT|NOT', '|', 5)

$Lstr_Parse returns the entire first argument longstring if none of the delimiter characters are found.
