WordNumberIn and WordNumberOf (String functions)

The word number of a word within a list of words (String class)

[Introduced in Sirius Mods 7.9]

The WordNumberIn and WordNumberOf functions return the word number of the first occurrence of one word (the "needle") within a list of words ("the haystack"). The search respects character case. The difference between the two methods is that for WordNumberIn, the method object string is the "needle" and the first argument is the "haystack", whereas for WordNumberOf, the first argument is the "needle" and the method object string is the "haystack". Which method is more convenient to use will be application dependent.

Note that processing a string of words may be better accomplished with the StringTokenizer class.

Syntax

%number = string:WordNumberIn( haystack, [Spaces= string])

%number = string:WordNumberOf( needle, [Spaces= string])

Syntax terms

%number	A variable to receive the number of the first occurrence of the needle word in the haystack list of words. If the word needle is not one of the words in haystack, %number is set to 0.
string	The method object string. Depending upon whether the WordNumberIn or WordNumberOf function is being used, string may be either the: search target needle, when called as WordNumberIn the search space haystack, when called as WordNumberOf
haystack	The list of words within which the needle is searched for.
needle	The word which is searched for in the haystack.
Spaces	A set of "whitespace" characters, that is, characters that separate words. The default is the blank character. If the null string is provided, the blank character is used as the whitespace character.

Examples

The following fragment:

PrintText {~='aa bb cc':WordNumberOf('bb')} PrintText {~='bb':WordNumberIn('aa bb cc')}

produces the following result:

'aa bb cc':WordNumberOf('bb')=2 'bb':WordNumberIn('aa bb cc')=2

You can use WordNumberIn and Word as "quick and dirty" NamedArraylists:

%x = 'PA' %w = %x:WordNumberIn - ('MA PA MN') %s = ('Massachusetts Pennsylvania Minnesota'):Word(%w) Print 'Full state name:' And %s

However, as the number of words grows large, repeated use of WordNumberIn is less efficient than using a NamedArrayList.
