"Negligible" in one program execution maybe. But it makes difference when
many executions and many programs take place. Beyond that, this is not a
good programming practice.
But yes, I am considering this solution (a GUI App). I will have to make
some performance tests to see it will be possible.
About running Windows, in this case, it is not my choice.

I really do not know how to do it in Delphi without the Graphics unit.
Beyond that the program is up and running.
My point here is to port or not from Delphi do Lazarus. I have other
applications to consider also.
