guaranteed to work only if you start with the latest *release*

Hi list,
A friend of mine started a hobby project:

I lack of the time for doing it at the moment, and I wish to add to his

Converting one of the answers there...

var

Date: TDateTime;
begin
for Year in [0 .. 5] do begin
for Month in [1 .. 12] do begin
Date := EncodeDate(Year,Month,13);
if DayOfWeek(Date) = 5 then begin
Sorry, missing one thing: Date := EncodeDate(StartingYear + Year,Month,13);

How to get all caller adresses of p1 in a program before p1 is executed?
For example p1 is called from 20 different places in a program.
Then I need the 20 caller adresses.

You know that scanning the binary code for calls is platform dependant?
Yes.
[calling opcode] [calleradress]
calling opcode can differ and the byteorder of the adress can differ.
So you'd need to write that code for every CPU you want to

f is just the STDOUT or logfile where the list of addresses is written

You might be able to do that sort of thing by running the program with a
profiler and analyzing all captured stacks. But it would be a vast
amount of effort, and unless you could guarantee 100% coverage (i.e.

I would guess that class vars are stored in the vmt already...
No, class var and regular variable has no difference except the scope.
It is a static variable which is shared between all instances and
descendants - so
