what are we even doing here man
if someone doesn't have experience with arrays, then they don't have enough experience with programming to hire them to program for you. they are still on page 9 of the programming book
Specifically, this one.
The Usborne guide to Better BASIC: a beginners guide to writing programs (1983)
See? Page 9. Arrays.
@foone That is how we learnt programming, with BASIC. Early home computers usually had an accompanying manual with a BASIC guide, as they shipped with a BASIC interpreter, at turn on.
