Use the list commands to index Director text chunks for operations where you otherwise would

have to refer back to the text itself. For instance you can use GetListOfWords to speed up a

proximity search (word 1 within so many words of word 2). List commands like:

if getAt(wordList,5) = secondword

are faster than text chunk commands like:

if word 5 of field "whatever" = secondword

GetListOfWords(sourceString) - where sourceString is the string to operate on. Returns a list of

character chunks delimited by white space or empty list if there was an error. Returns a list of

character chunks in the string delimited by white space. White space includes TAB(9),

Linefeed(10) and Return(13).

Example:

on makeIndex thestring

-- Create an alphabetical index of the words

-- in a text chunk

set index = [:]

set thestring = ToLowerCase(thestring)

set wordList = GetListOfWords(thestring)

if TC_GetLastError() = 0 then

set numWords = count(wordList)

repeat with w = 1 to numWords

set thisword = getAt(wordList,w)

if voidP(getaprop(index,thisword)) then

addprop index,thisword,list(w)
