A Little Repair Work

It is always exciting to find that someone actually reads this blog!  Recently, one of Paul Kimple's friends, a youngster from the transistor age and the Burroughs B-5000 tried out Paul's emulator with my Prime Number Test program that is found in the right hand column of this blog just below the link to the emulator.

Unfortunately, I had been careless in creating this program and it didn't identify even numbers as being non-prime.  It also didn't handle inputs of 0, 1, or 3 very well either.  I repaired it this afternoon to correct these errors.  Kudos to Jim Fehlinger for finding the errors and reporting them.
