So, Result becomes 10.
Yes, that's what happens and, yes it's a misspelling by one of our end
users. Basically we use FPC as one of the engines for the scripting part
of one of our applications.
The next line is a function call without storing the result. The
leading '+' (plus) is seen as sign; since '+' is neutral, it seems to
be ignored by the compiler. A '-' (minus) would force some action, so
it is absolutely wrong at this place.
Thanks for the explanation on the behavior.

Subject: [fpc-pascal] Weird absence of compilation error
Hello all,
I'm using FPC 2.6.0 and have the following test program :
program test;
function Element: Double;
begin
Result := 4;
end;
function Tmp: Double;
begin
Result := 10; + Element;
end;
begin
WriteLn(Tmp);
end.
And quite surprisingly to me, both ppc386 and pccrossx64 compile it
successfully in Delphi mode!
What's even weirder is that if I replace the Plus operator by a Minus
operator, then the compilation fails.
What I was expecting is that the compilation fails in all cases.
Is there some flag that I failed to specify?
Regards
OBones
