Return a word from a long string
Note: Most SOUL $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.
Syntax
%result = $Lstr_Word(longstring, n, delims)
%result is a Longstring that is the nth word in the longstring argument.
longstring is an arbitrary Longstring. This is a required argument.
n is the number of the desired word. The first word in the longstring input is word 1.
delims is a string containing from 1 to 255 characters which are the delimiters for longstring. This is an optional argument, and it defaults to a blank.
Examples
- To set %res to "shore":
%res = $Lstr_Word('She sells sea-shells by the sea shore', 7)
- To set %res to "sea":
%res = $Lstr_Word('She sells sea-shells by the sea shore', 7, '- ')

- WordCount — Count words in list
- WordNumberIn and WordNumberOf — Word number of "needle" word within "haystack" list of words
