For this little routine that used the SOLVER feature will shown three soft menu on display for easy access as [RATE] [A] [B] The RATE amount is always there until user change it.  Formula used: (A x RATE)  B = 0 Where A is the Original B is the New  Procedure: [Orange Key] [SOLVER] [EXC] Display shown soft menu: [RATE] [A] [B] Set Rate Amount and either [A] or [B]  Example: Exchange Rate between USA and Japan $1 = 107.05 [SOLVER] [EXC] 107.05 [RATE] display RATE=107.05 To check: 1 [A] display A=1.00 [B] display B=107.05 This will let you know that [A] is USA and [B] is Japan  $55 is how much in Japanese Yen? 55 [A] display A=55.00 [B] display B=5,887.75  10,000 Yen is how many US Dollars? 10000 [B] display B=10,000.00 [A] dispaly A=93.41  Program: Code:
