In order to testing the calculator I wrote these simple programs:


add.prg -> sum X with Y
double.prg -> 2 * X value
sum10.prg -> calculates 1+2+3+4+5+6+7+8+9+10
scores.prg -> Mean of 2 numbers. Write the first number, then run the
              program.
              When the program stops write the second number and press
              [R/S]
              The answer is shown.

show1to10->  Shows the numbers 1 to 10.

             If between some numbers you see the ">-", then you need
             to put a lower value in the child window configuration at
             delay after GTO. The current value is 1000000 . Write
             500000 or less and restart the emulator.

constant.prg -> Fills the stack with a number in order to be used as a
              constant.

fillregs.prg -> Fills register 0 to 24 with the same number provided
              before running the program.

              Load this program. Enter the number and press [R/S]
              In this prog. you see Rv. This is the same that RDN 
              When the program ends, open the memory child window
              and view the contents.


(I wrote much more programs for testing and I will include them in
future versions).
