When the IT Dept gets rid of computers they either trash the hard drive and throw them away or give them to a recycling computer company to hipe the HD and resell them.  You should look into it.

I have found some amazing deals with off-lease computers.  Ubuntu, Linux Mint or another easy *nix might be suitable for you for these purposes.   :)

Thanks for the idea on using #define for constants... I should have known better. :P

I'll post the updates soon.  Never know when you need to know how much your butt weighs on the Moon!  or Uranus...   :P

HELLO.

This is due in my CIS C Programming class soon.  I thought it would be no sweat, but I ran into some trouble at the end because I cannot break out of a switch when the switch/case is inside of a while loop.  If you have any code suggestions please let me know.  I probably went about it wrong.  Maybe I should have used a flowchart or something. 

ok.  whatever.. have a look.  thanks.   :D
