It was IMO obvious that this construction would make a program larger. But
my intention is to pinpoint these kind of things in subroutines. When using
heapreallocation, I will add subroutine A to the binary, otherwise B.
Using your own example the extra size is 12 bytes. I can live with that. The
number of times I have to call the subroutine will be the real impact on the
speed.

This advice has been given to many programmers, inventors etc. Of those who
didn't listen only some succeeded against all odds. I hope to be one of
those some :)
But one important reason is that I already learned things about using Pascal
in other ways (hardly used pointers before).

This I already had in mind by generating (pseudo-) assembly.

I have no idea at all at this moment how I can optimise code. But at this
moment I even cannot generate code, so this has to wait until I can :)
