Welcome to proCALC for Newton v1.1

If you are upgrading from v1.0 please ensure you delete 1.0's
preferences (via the prefs window) before you install v1.1

Even though the Newton shipped with a built in calculator there was 
early demand for a scientific calculator. Although there have been 
a number of shareware and commercial offerings I have found them 
either awkward to use or difficult to look at.
proCALC addresses these shortcomings and provides several unique 
features including:

 Reassignment of the Newton built in calculator icon 
 (doesn't clutter the extras draw with its own icon)
 
 Aesthetic and functional emulation of a "real" calculator.
 (yes I know the off switch is a Newton user interface crime 
 but the HP33 didn't have a close box :-))
 
 Observation of operator precedence 
 (ie 1+2*3 = 7 not 9)
 
 Over 50 Scientific and financial functions 
 (inc DEC and HEX conversions)
 
 Evaluation of arbitrary NewtonScript expression sequences 
 (eg 23+(3.4*sin(30)), GetGlobals().userconfiguration.company:="Acme" etc)
 
I suggest you install proCALC's owners manual and read it.

Registration will provide you with a full working version of proCALC,
free upgrades to future versions and preferential information 
on new products.

If you don't like proCALC then please let me know so I can address that. 
I am committed to improving proCALC for you and your feedback (be 
it cash or comments) will ensure that. 

I don't want proCALC to get too "kitchen-sink" like and will include
features based on user demand.

Possible future features include:

 RPN logic
 BIN,OCT,HEX conversions with arithmetic
 More functions (%T, x<->y etc)
 Statistics (mean, SD etc)
 Programmability
 Ability to disable operator precedence
 Paper tape (does anyone actually use this?)
 Iconification
 User definable constants
 proCALC using the full screen (with 2 line display and bigger buttons)

I hope you find proCALC useful

Enjoy!
