Are you referring to the text-based IDE?  It's not what I had
in mind.  Add to my list two more requirement:

- fully integrated with a modern, graphical, window system
- understandable error messages

It has to allow me to use all the area on this big monitor.
RHIDE sup****ts a max of 80x98 characters in its window system.

I tried a simple test case and didn't get useful
debugging info.  I'm typing this from memory - sorry if
this doesn't compile.  FPC gives mysterious messages
about "runtime error 216 at address $0040104a" and the
editor doesn't jump to line 11 where the error was.

program learning;
type
  t = record
    a : integer;
    b : real;
  end;
var
  x : ^t;
  s : string;
begin
  writeln( x^.a ); // Should get a "NIL pointer" error.
  new( x );
  writeln( x^.b );
  s := 'abcd';
  writeln( s[5] ); // Should get a "range" error.
end.
