ProSum Bugs Found with Blink Test
Earl Everett told me that I was the first person he had seen do this
test to find those bugs. Imagine how difficult it would be to find
those bugs using any other approach (other than code inspection. But
hey, I'm talking testing, here).
- Negative numbers appear in the lower field only.
- "100" appears occasionally in either field, but the allowed range
is -99 to 99.
