The lookup table is interesting. I wonder why pretty much no 1980s home computer BASICs included bitwise operations?

- RiverCrochet 5mo agoThey did. AND, OR and NOT were bitwise operations as well as conditional operators. E.g. POKE 254, PEEK(254) AND 127 would turn off bit 7 of memory location 254 without affecting other bits.
- ErroneousBosh 5mo agoIn which BASIC?
- RiverCrochet 5mo agoAll the Commodore BASICs, Applesoft, GW-BASIC, QBASIC from what I remember. Very certain about the Commodore BASICs.
- ErroneousBosh 5mo agoI did actually know that Commodore BASIC had it but had forgotten. I don't think I'd ever used GW-BASIC or QBASIC, weren't they on PCs? Apple IIs weren't really a thing over here although the very first home computer I ever used was an Apple II belonging to a friend of my mother's - Tony van der Kuyl, father of video games magnate Chris van der Kuyl ;-)
