Why is this an issue?

Parameter declarations should not be grouped together. This affects readability, is less convenient to change for version control purposes, and can be error-prone to modify.

How to fix it

Separate the grouped parameters explicitly:

procedure MyProc(MyName: string; MyId, MyAge: Integer);
begin
  // ...
end;

procedure MyProc(MyName: string; MyId: Integer; MyAge: Integer);
begin
  // ...
end;

If the grouped parameters are const, var, or out parameters, make sure that each parameter has the same keywords after separating: 

procedure MyProc(MyName: string; const MyId, MyAge: Integer);
begin
  // ...
end;

procedure MyProc(MyName: string; const MyId: Integer; const MyAge: Integer);
begin
  // ...
end;
