Return the position of a word within a long string

Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for $Lstr_Windex is WordNumberIn. Or, you may find the features of the StringTokenizer to be more helpful.

This function takes a string or longstring input and returns a number indicating the word position of the second argument within the long string. If the word is not present, zero is returned.

The $Lstr_Windex function accepts three arguments and returns a string result.

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

The second argument is an arbitrary string containing a single word. The word must have no occurrences of any of the delimiters in argument three, and may not be null. This is a required argument.

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

%result = $Lstr_Windex(longstring, word, delims)

%result is the position of word within longstring.

Examples

  1. To set %RES to "6":

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

  2. To set %RES to "3":
