Look at the top. The programmer must be aware of the two meanings and add a
unique identifyer in front of the text. What you want to discuss here is
specific and (more or less) deep. You want from me immediately a solution to
all this kind of specific things.

See above. You can also add a unique identifier if you want.

Yes at programstart with searching the opcode for calls and loading the pchar
const in EAX.
Post from 11.08.2012 which is searching the caller adresses of a given
function (parameter proc_adr). With another piece of code I can get the
pointer of all pchars if this proc has one pchar parameter.
procedure i_really_know_what_i_am_doing( p_opcode : pbyte ; count : longint ;
proc_adr : pointer );
call_opcode = $e8;
caller_adr_pc_offset = 5;
p_reladress : pdword; // call works with a relative adress after the opcode
x , caller_adress , jmp_adr_abs : dword;
for x := 1 to count do begin
if p_opcode^ = call_opcode then begin
p_reladress := pdword( p_opcode + 1 ); // after
opcode = relative adress to procedure/function to call
caller_adress := dword( p_opcode + caller_adr_pc_offset );
jmp_adr_abs := caller_adress + p_reladress^; // absolute
adress = programcounter + 5 + relative adress
if jmp_adr_abs = dword( proc_adr )
then add_caller_adress_to_table( caller_adress ); // if call
proc_adr then found!
inc( p_opcode );

Until now I did not come in contact with that.
I don't know if it is necessary for me.
So I don't need to spend the time now for that.
But I am confident that there will be a solution for that.
