Handy Calc is a scientific calculator for Windows.

To install Handy Calc click on the 'File' menu of your Windows Program 
Manager, and select 'Run'.  Then type a:\setup (or correct path to SETUP.EXE) 
and press 'Enter'. A dialog box with source and destination paths should 
appear.  Check to make sure the source and destination paths are correct and 
press OK.  It can take a minute or two to install.

SETUP.EXE will copy Handy Calc to your hard drive (if needed) and create an 
icon for it.   

You can install Handy Calc manually by creating a directory (such as C:\HANDY) 
on your hard drive, copying all the Handy Calc files into that directory, 
and creating an icon for HANDY.EXE in Windows.
