Description

Tests to see whether all possible factors have been tried. If all factors have been tried, branches to the display routine.

Calculates the next possible factor, D + 2.

Branches to test potential prime with new factor. Checksum and length: 161E 57

Flags Used:

None.

Program Instructions:

1.Key in the program routines; press when done.

2.Key in a positive integer greater than 3.

3.Press XP to run program. Prime number, P will be displayed.

4.To see the next prime number, press g.

Variables Used:

PPrime value and potential prime values.

DDivisor used to test the current value of P.

Remarks:

No test is made to ensure that the input is greater than 3.

Example:

What is the first prime number after 789? What is the next prime number?

Miscellaneous Programs and Equations 17–9
