It's mostly a historical difference..pas are units that could
(originally) be compiled with Turbo Pascal as well (which is why all
units of the compiler use .pas) while .pp was designated for units
that can only be compiled by FPC (which is why the old units of
the RTL are called .pp). There is no technical difference between
them. And for compatibility with Mac or Apple Pascal FPC also
supports .p (this extension can be seen in the Photoshop 1.0 source
for example).
Today .pp is used for example for FPC's test files (also for new ones)
out if habit.
I think you are under a misapprehension. It is not 'out of habit'. I use
.pp for all my contributions, out of principle.
Then let me rephrase my last sentence:
Today .pp is used for example for FPC's test files (also for new ones) either
out of habit or out of principle.
Better now? :)
You are taking this far too serious :-)
But as a tip:
if the code is for FPC only, use .pp.
It's more efficient, because the compiler first looks for .pp files, only then .pas.
