Return a word from a long string

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for $Lstr_Word is Word (except that Word does not allow a word number argument less than 1, as does $Lstr_Word.) Or, you may find the features of the StringTokenizer to be more helpful.

This function takes a longstring input and a word number and returns a longstring containing a single word. A null string is returned if the word count in the input longstring is less than the word number.

The $Lstr_Word function accepts three arguments and returns a longstring result.

The first argument is an arbitrary longstring. This is a required argument.

The second argument is the number of the desired word. The first word in the input longstring is word 1.

The third argument is a string containing from 1 to 255 characters which are the delimiters for the longstring. This is an optional argument and defaults to a blank.

Syntax

<section begin="syntax" /> %RESULT = $Lstr_Word(longstring, n, delims) <section end="syntax" />

$Lstr_Word function

%RESULT is the nth word in the longstring.

For example

%RES = $Lstr_Word('She sells sea-shells by the sea shore', 7)

sets %RES to "shore" and

%RES = $Lstr_Word('She sells sea-shells by the sea shore', 7, '- ')

sets %RES to "sea".

$Lstr_Word is only available in Sirius Mods Version 6.5 and later. Prior to Version 7.3 (or Version 7.1 or 7.2, with maintenance applied), if the result of $Lstr_Word was longer than 255 bytes, either the request was cancelled or the result was truncated at 255 bytes.
