the following unit throws an (I think wrong) compile error "Duplicate
identifier 'Connection'". This happens Lazarus with 2.0.8 under Win
10 (64). According to Nicklaus Wirth and Kathleen Jensen ('Pascal
User Manual and Report') there is no duplicate identifier in this
unit, since 'Connection' in procedure Proc ist strictly local and
does not interfere with Identfiers outside this procedure.
You are aware, that this manual was way before Object Pascal?
Code:
unit DoubleDefinition;
{$mode objfpc}{$H+}
$mode objfpc is more strict on duplicates.
FPC supports other modes like $mode Delphi, which allows this
duplicate.
Mattias
Here there is no Duplicate Identifier error message:
program Duplicate;
{$mode objfpc}{$H+}
var TestVar: string;
procedure Proc;
var TestVar: string;
begin
TestVar:= 'zwei';
writeln (TestVar)
end;
begin
TestVar:= 'eins';
writeln (TestVar);
Proc
end.
Why this inconsistency?
