Remarks

var
  int1, int2: integer;
  str1, str2: string;

var

var
  str1, str2: string;

Variables with different types must use the var keyword for each type

const
  int1, int2: integer;
  str1, str2: string;

const
  int1, int2: integer;
const
  str1, str2: string;

Constants with different types must use the const keyword for each type

SetLength(ARRAY_OR_STRING, NEW_LENGTH)

ARRAY_OR_STRING.SetLength(NEW_LENGTH)

The SetLength() method can't be used for arrays anymore

Print 'VALUE'

Print('VALUE')

The Print() method requires parenthesis

procedure proc1();
begin
  proc2();
end;
procedure proc2();
begin
end;

procedure proc2();

end;
procedure proc1();
begin
  proc2();
end;

If a procedure calls another one, it must be declared before that method. Alternatively, proc2 can be declared before proc1 as a forward method: procedure proc2; forward;
