mode.
To run the program press (f][C]. The calculator will display a table
of integers from 1 to 10 with their corresponding square roots.
When 0.0000 is displayed, program execution is completed.
How It Works: When you press [C], the calculator searches
through program memory until it encounters the
instruction. It executes that label and each subsequent instruction
in sequential order through line 014, the conditional test. If
the result of the conditional test is true—that is, the last
integer used was less than 10—the following 0 instruction is
executed, the calculator returns to the 0 instruction at line 004,
and execution resumes as a new iteration of the loop. However, if
the result of the conditional test is false, meaning the last
integer used was 10, the 0 instruction is bypassed and the
loop is terminated.
For an additional discusssion of looping and loop control
techniques, refer to page 214, Looping, in part III of this handbook.
Problem. Write a program to calculate and display sales
commissions. For sales of less than $100 the commission should be
10% of the sale. For sales of $100 or more the commission should be
15%. Use a conditional branch in your solution.
