I am having a problem using Munger in a macApp program I'm writing.  I
am trying to use it as part of a simple text-parsing routine.  Here is
an example of what I have now:

Given:

	VAR
		aChar : Char;
		text : Handle;
		offset : LONGINT;
		where : LONGINT;

I have text set correctly (I've checked this), and offset set to 0.  
I then try to find the first tab character in a string which I know 
contains at least one tab using:

	aChar := chTab;
	where := Munger(text, offset, @aChar, 1, NIL, 0);

but Munger returns -1, signifying that the string was not found.

Am I doing anything wrong?  According to my reading of IM, it should be
OK.
