Trouble porting liquid simulation to Pascal - AARRGGHH!

[Ingemar]

I believe there is a setting in Lazarus (and I guess freepascal too) where you can use +=, -=, etc. operators, but I don't know about ++ and --

Correct, and += and -= are pretty useful. ++ and --, however, I'd rather live without, especially when used for throwing in side effects while doing other things.

You even have << and >> in FPC. It is sensible, the few times where C syntax makes sense there is no reason not to incorporate it. But finding C-style "for" loops is something that was supposed to be working Pascal code, that was scary. One detail that makes me uncertain is the ability to spread variable declarations all over the place. Should variables be at one place or anywhere? Defining a variable locally within a for loop or inside a begin-end pair, well, not entirely unreasonable... or is it just a workaround for messy code, when C programmers write entirely too big functions?

Anyway, now that I know what files to look for I can compare what we do.
