Thank you for the help. Unfortunately I'm now confused even more. I

You can always modify them (it's just data in memory), but modifying them
will only change your private view of the variables. The changes you make
will

I do not agree with this interpretation.
First of all, you are calling execv() in your code, not execve(). That libc
changes this to execve() is IMHO not permissible.
So all bets and conclusions are off from that point onwards.
Why not permissible? The

Hi guys,
I try to start itself again with this code, but it doesn't work:
IF GetEnvironmentVariable('LIBOVERLAY_SCROLLBAR') '0' THEN begin
mProc := TProcess.Create(NIL);
mProc.CommandLine := GetExeName;
mProc.Environment.Add('LIBOVERLAY_SCROLLBAR=0');
