Okay, I pretty much guessed what this was for. I assume this is similar to OORexx's [do] "over". Of course, here's what I really found funny, which even marcov must be aware of:


[ WinXP ] Tue 11/23/2010> type hello.pas
program hello;
var c: char;
begin
for c in ['a','e','i','o','u'] do writeln(c)
end.

[ WinXP ] Tue 11/23/2010> fpc hello.pas

u

[ WinXP ] Tue 11/23/2010> for %c in (a e i o u) do @echo %c
a
e
i
o
u


DOS lives! :rotfl:

EDIT: Barely surprising that someone else had almost the same lame test code as me. And surely there are better uses for this feature, heh.
