Hi.
	I am trying to write an epr simulation program using Prototyper to
generate the Mac User-interface.  I have the simulation code that actually
does the numbercrunching working nicely, and thought I'd put a nice interface
on the program, letting Prototyper do most (all? or is that being to hopeful?)
of the work.  I have run up against a little problem with data entry:  I
made a dialog box in Prototyper to allow the user to enter in all the 
numerical parameters the user needs to run the simulation.  I generated the
Pascal code, and compiled the sucker in Think Pascal.  The problem is that
the call that actually gets the info from the dialog box (GetItext, or some
such thing), puts the data into a STRING variable.  I unfortunately need a 
REAL value here!  There would be no problem if I needed an integer, since
StringToNum would do the trick (I guess).  Does anyone know if there is
a similar function to convert to a real-type value?  Or, is there a way to
get real-types *directly* from the dialog?

	Since the dialog approach would be the best interface for entering
parameters, and I *know* *lots* of programs use that way for entering data,
I'd be *greatly* appreciative if anyone could steer me in the right direction!

Thanks in advance,
