CalcPad is a small Windows scientific calculator program.  CalcPad runs 
on Windows 3.1 or higher.

It is obvious that forcing a computer to mimic the shortcomings of a 
calculator is rather unwise, yet many calculator programs for Windows 
do exactly that.  Such shortcomings include no visual feedback after 
some of the key inputs, not able to back up to an earlier line and edit 
the result, single memory storage, etc.

The main advantages of CalcPad vs. the Windows MiniApp Calculator are:

  o  An editable input text window.
  o  A scrollable output pad allowing errors be corrected after the 
	 expression is evaluated.
  o  Diagnostic messages for errors in expressions.
  o  A variable list that can be modified.
  o  Interface with the clipboard.
  o  Does not mess with the win.ini file.  CalcPad uses a .ini file
	 in its own directory, keeping your windows directory clean.

To install CalcPad, copy the three files, CalcPad.txt, CalcPad.exe and
CalcPad.hlp into a directory of your own choice, such as c:\calcpad.  
Then in Windows, create a new program item in the Program Manager.

The CalcPad interface is intuitive, but help is still available on 
line.  Just start the program, and press "F1".  Most of the document 
can be viewed by using the "browse buttons", which are marked with ">>" 
and "<<" in the help utility.  You can also find my address through 
the on-line help.

Version 1.2 uses less memory and disk space, does not use a start-
up windows any more, and remembers its previous window locations 
(registered version only).  Version 1.4 corrects a few bugs in version 
1.2, none of which affects calculation accuracies.

CalcPad is freely distributable and its distribution is encouraged.  If
you are a registered user, however, your copy of the calcpad.ini file 
should not be shared with others as it contains your personal data.

Enjoy.
