(*
{How to write next by pointers:}
pStartupInfo.cb:=$44;
pStartupInfo.lpReserved:=nil;
pStartupInfo.lpDesktop:=nil;
pStartupInfo.lpTitle:=nil;
pStartupInfo.dwFlags:=$81;
pStartupInfo.wShowWindow:=$0A;
pStartupInfo.cbReserved2:=$00;

{I've tried :
attempt 1:
@pStartupInfo^:=dwaM4;
@(pStartupInfo+$2c)^:=dwaN3;

attempt 2:
p:=@pStartupInfo;
p^:=dwaM4;
(p+$2c)^:=dwaN3;
But some convertion errors appears ... :(
}

eny:
No idea what you want to do.
Maybe something like: pStartupInfo^.cb:=$44;

Blaazen:
Yes, we don't know if your pointers are typed or untyped.
Anyway, this works.

--- Code: ---type TMyRec = record
a: LongInt;
b: LongInt;
end;
PTMyRec = ^TMyRec;

var PMyPoint: Pointer;
PMyRec: PTMyRec;

.........

PTMyRec(PMyPoint+8)^.a:=20;
PTMyRec(PMyRec+16)^.b:=80;
PMyRec^.b:=50;

--- End code ---

marcov:
Use move()

something like

--- Code: --- move (constant1, startup,sizeof(constant1));
move (constant2, (pbyte(@startup)+sizeof(constant1))^);

--- End code ---

or

--- Code: --- pdword(@startup)[0]:=0;
pdword(@startup)[1]:=1;
pdword(@startup)[2]:=2;
etc

--- End code ---

I want write pStartupInfo directly in memory. I don't want to use record fields like .cb .lpReserved so on.
pStartupInfo-record's fields are represented in memory like this:

I want find addresses of these records and write 7 dwords:
