CHARACTER POSITION

The return values of the Find commands would not be very useful unless you had some way of

fetching the found word back out of the Director text chunk you were searching. These

commands, in tandem with the Find commands can be used to do things like highlight the found

word in a Director field or display the found word in context with the other words on the same

line.

GetWordOfCharPosition(sourceString,characterNumber) - where sourceString is the string to

search in and characterNumber is the integer character position in the string. Returns an integer

word number in sourceString of word containing the specified character position or 0 if no word

contains the character position or if there was an error. Converts the character position returned

by one of the Finds to a word number in the text chunk.

Example:

on showWord fieldName,theWord

-- Finds a word in a field and highlights it

set charPos = FindNext(field fieldName,theWord)

if TC_GetLastError() = 0 then

set wordNum = GetWordOfCharPosition(field fieldName,charPos)

if wordNum > 0 then

hilite word wordNum of field fieldName

end if

end
