<I've seen TeX compiled by Turbo Pascal (TeX is written in Web, which can <be converted into Pascal). IIRC it had to be split into sections to get <over the 64K code limit of TP. I still have problems with the idea of <running it _with enough space for the various variables_ in a 64K machin The conversion process and pascal compiler adds weight. <LaTeX is just a set of macros that run on top of TeX. I can assure you I <know the difference. And how early? Before TeX82? 1979. <TeX in itself has no idea what a printer is. It produces a DVI file whic <is essentially a binary file describing which characters and 'rules' <(lines) have to be put where. There's a printer driver which takes a DVI <file and outputs the code for whatever printer you have. Understood. Did a lot of work in printing for DEC and none slower than 12ppm. The DVI is essentially a bit map and as a result for godd page can be quite big. However the virtual window to disk file works and is adaquately fast. Allison
