Brett,
To answer your question, how can you apply the handler each time you
access your external file...
Your handler is set up as a function that returns a value. So, instead of
saying
setPref("myPref.txt", myVar) --(from a variable), or
setPref("myPref.txt", member("myText").text) --(from a text element),
etc.
you simply call the handler in that spot--passing the text, inside
parens, to the "source" argument in:
setPref("myPref.txt", CRLF2CR(myVar)) --or
setPref("myPref.txt", CRLF2CR(member("myText").text))
The handler returns the cleaned value and setPref can finish.
I'm not sure exactly what you want your handler to do. Your handler
strips out all ASCII char 13 which is a carriage return. Similar handlers
I've used in the past check the platform and alternately address the
numToChar(13) and numToChar(10) which is a line feed. Your handler
mentions that in a comment, but implies it was changed previously.
Also, if you want to add the carriage returns back in for a getPref read,
you'll need to deal with that, at some point, too.
If none of that is an issue, you should be good to go with the above.
