FPC forces the ^ operator while accessing structures as pointers.
Delphi didn't force it and I even suspect that memory leaks can result
in NOT using the ^ to denote the reference to the pointer rather than
the pointer itself.
This was just discussed in another thread. This is not always forced by FPC.
eg:
var
S: TMyArray;
pS: ^TMyArray;
then use them as follows:
S[2]
pS[2]
Both work just fine without dereferencing the second line. Weird
behaviour, but true.
However they have a different meaning.
assume TMyArray=array[1..10] of Byte;
then S[2] refers to the second element of S, being the second byte,
while pS[2] refers to the 3 element of pS, being the 3rd TMyArray
