Instruction
Example of Conditonal Loop Control. The following program
calculates and displays the square roots of consecutive whole
numbers from 1 to 10. After the square root of an integer is
calculated and displayed, an conditional test determines
whether or not that integer was less than 10. If the integer was less
than 10, a 0 conditional branch is executed and the loop is
repeated using the next highest integer. If the test finds that the
integer was not less than 10, program execution bypasses the
0 conditional branch and the loop is terminated. (The loop portion
of the following program is included in lines 004 through 015.)
