Re: Pascal for ZX81

Since I got hold of the manual I've used the weekends to play with and investigate Partial Pascal. I wondered if the object code generated with Partial Pascal was machine code with calls to a Pascal library, or tokens that needed an interpreter. The below listing contains 3 prints: First is output f...

Re: CHR$X16

Unfortunately it's also sold out at the moment. :(
