Reddit mentions of Chip Mitchell : The Case of the Chocolate-Covered Bugs

Learned BASIC from math textbooks, 3-2-1 Contact! magazines, which actually printed an editor chosen submission of a game every month which is awesome, and the Chip Mitchell book series, which was kind of like Encyclopedia Brown except that the case answers were sometimes code debugging puzzles. The funny thing was, I didn't actually start using QBasic until a few years later, but I remembered so much from these that I was able to write up code consisting of PRINT, INPUT and IF statements purely from memory.
