BEGIN_RDME qed_2.rdm

Hi!

I was very surprised when I heard that QED 1.06 seemed to crash when
some libraries were installed. The reason for this is simple, but it
is not that easy to solve the problem. QED really needs absolute
adresses in RAM. But since it is no longer self-modifying, as it has
been in version 1.05, I needed to find a save location were to put
the internal variables. QED uses the PICT memory, which I guessed
to reside in the same place any time. But there are some libraries
that moves the PICT memory to a higher location - in general a few
bytes only, but this caused nasty crashes. The solution is not
that elegant, but I think it will prevent further trouble:
QED uses now the highest possible memory-range, and it checks wether
this range is occupied by PICT or not. So I managed to make
QED work with all the libraries I tried - and I hope it will
not crash anymore...

cu, Lutz Vieweg
