Assume that I have a pointer to a record pR, and wish to access one of its members (e.g. mem1), how do I do that? Does it work with both ways: pR^.mem1 and pR.mem1 ? (It seems to be compiled and ran ok in both ways) If so, for what purpose do we need "^", except when declaring the pointer type itself. Thanks, Tal.

Hi Tal, For what I know the "^" symbol stands for "content of the cell wich the pointer type points to"... That is, the data pointed by the pointer variable. If I remember well, in older versions of Delphi, if you didn't use the "^" you would not get your source compiled. Since some time, for sure in Delphi 7, you can reference your data with or without the "^". The compiler itself will resolve the reference. In few words, you can still keep on using "Pointer^.Member" or "Pointer.Member". Personally, I prefer to use "Pointer^.Member" style, becuase it remembers me that I'm dealing with pointers and that somehow / somewhere I will have to free the pointer variable with a Dispose.
