My first computer I could swear I’ve written about this before, but I can’t find it, so it must’ve never escaped Twitter

Program 4 appears to simulate a one-second delay with a 630-iteration empty loop. There is, of course, nothing explaining why this is the case. 630 might have been my very first magic number.

• Program 8 is an implementation of selection sort! This is the only use of DIM — the statement for declaring an array — in the example programs. I remember being very confused as to what DIM even did, let alone realizing the point of the program. None of them have any kind of explanation or comments, except for a couple comments dividing up the rather long program 9.
