    4.7 CONVENIENT PROGRAM COMMANDS The programs for this unit are made based upon manual calculations. Special program commands, however, are avai- lable to allow the selection of the formula, and repetitive execution of the same formula. Here, some of these commands will be used to produce more convenient programs. 4.7.1 Jump commands Jump commands are used to change the flow of program execution.

Example: calculate y=ax+b when the value for x changes each time, while a and b can also change depending upon the calculation. ?, →, A, : , ?, °˙, B, :, Lbl, 1, :, ?, →, X, :, A, x, X, +, B, , Goto, 1 23 steps...
  • Page 58 In this program, a 0 is first stored in memory B to clear it for calculation of the sum. Next, the value input by “? I A” is stored in memory A by “A=0⇒” and it is determined whether or not the value stored in memory A equals zero.
  • Page 59 Example: Determine the altitude at one-second intervals of a ball thrown into the air at an initial θ t - 1/2gt velocity of V(m/sec) and an angle of S°. The formula is expressed as: h = Vsin , with g=9.8, with the effects of air resistance being disregarded.

When using the standard memories, the input value is compared one by one with the value assigned to each memory ( e.g. A=1, B=2,ˇ) With the array-type memories, the input value is immediately stored in the proper memory determined by “[Z-1]”.
  • Page 63 As can be seen, the second displayed value (which should be 2) in A[2] is incorrect. This problem has occurred because memory A[2] is the same as memory C. A[1] A[2] A[3] A[4] A[5] The content of memory C (A[2]) is decreased from 5 to 0 in steps of 1. Therefore, the content of memory A[2] is displayed as 0.

However, since memory names are restricted to the letters from A through Z, the expanded memories ( ) can only be used as array-type memories.

    This program calculates the x power of 2. A prompt of “N=?” appears for data input. The result is displayed by pressing while “X=” is displayed. When an input data is not the x power of 2, the display “NO” appears and execution returns to the beginning for reinput. *** Always follow a message with a whenever a formula follows the message.
