A Question about the list manager and modal dialogs.

I am trying to put a scrolling list into a modal dialog;
the problem is that my repeat loop goes 10 or 12 times
and then a system error of some kind occurrs.  MacsBug
says that the program counter is 0 at this point.

My repeat loop looks like this:

repeat
    modalDialog(@listFilter,itemHit);
until itemHit = OK;

The filter proc isn't doing anything because this happens
when I just start the dialog and wait, and it ignores all
but mouseDown and keyDown events.

Alternately, I seem to get an ADDR ERR 00000001.  Does
this mean that I am trying to address something at byte 1?
I'm not sure how many times the repeat loop goes in this
case.

I'm using Turbo Pascal on an SE.  (I know, I should switch
to another language, but ... )

Thanks for any assistance you can give me!

P.S. Can someone suggest a) a better debugger for use
with Turbo Pascal, and b) why the {D+} compiler directive
doesn't seem to make a damn bit of difference.
