[Solved] pointers

[Ten_Mile_Hike]

I know the BASICS of pointers, but I'm just playing around ---and wondered;
if the value of memory location of A below is 341576016 how can I display that in pascal?
I've tried ABSOLUTE and did get a  7 digit value back, but I don't know if that is valid.
If not in pascal, how about inline ASM?

AGAIN...I'm just goofing around. Not trying to program anything

Thanks

Code: Pascal  [Select][+][-]

1. var
2.   A:Integer;
3.   A_Ptr:PInteger;
4. begin
5.   A:=77;
6.   A_PTR:=@A;    
7.

Writeln(IntToStr(A_Ptr^));

The actual address stored in the pointer:

Code: Pascal  [Select][+][-]

1. writeln(IntToStr(PtrUInt(A_Ptr)));

Or "IntToHex" if you prefer.

PtrUInt will be QWord or Cardinal (or ...) depending on what bitness you compile for. So you can always use this to cast the pointer into a number.

In addition, and in case not wanting to rely on sysutils:

Code: Pascal  [Select][+][-]

1.   WriteLn(HexStr(A_Ptr));
2.

There is also format() with P type argument,
see: https://www.freepascal.org/docs-html/rtl/sysutils/format.html

Code: Pascal  [Select][+][-]

1. uses SysUtils;
2. .............
3. Writeln(Format('%P',[A_ptr]));
4.

Format is overkill:

Code: Pascal  [Select][+][-]

1. var
2.   b:PtrUint = 12345;
3. begin
4.   writeln(b);            // value
5.   writeln(PtrUint(@b));  // address
6. end.

Thank you everyone for your responses.
I greatly appreciate it.
