I guess today is Pascal's day.

This website is full of goodies for anyone that cares about history of Niklaus Wirth created languages.

Pascal will always have my heart. My first bridge outside Basic (I was stuck with a home pc so didn’t go down the assembly rabbit hole like others of my generation). Turbo Pascal’s IDE. Add it possible for a kid to learn and create in a way I never would have done if stuck with a collection of semi independent tools. for those who say just use the command line - this was 1989. DOS was not exactly today’s modern shell environment!

Simlar language, compatible with MSDOS, CP/M and Unix:

Early versions (3?) could fit an amazing editor, assembler, compiler, debugger and whole IDE in just 120kb(!!!) of disk space.

Vim looks pathetic in comparison to it...

Another blast from the past with these machines. Nice post!

Wait, you had working inline assembly in the old Turbo Pascal 3.0? I never knew.

I purchased Turbo Pascal 3 for Amstrad CPC 6128 with my pocket money back in 1989(?). That was 1000 FF back then (~275€ today) so quite a big sum for a teenager. My dad took pity on me and funded 50% of it. Best investment ever!

Learning Pascal after Locomotive Basic was night and day. And the speeeeeed! I could finally compute 320x200 Mandelbrot set renderings in reasonable amounts of time (few minutes IIRC).

I still have the disk & manual somewhere, as well as a couple related books. And for whatever reason Ctrl-K Ctrl-W still haunts my mind.

It's really mind boggling that the entire thing (CP/M + IDE + compiler + libraries) fit on one side of a 3" floppy disk (<180 kB).
