I did read Vermaak's example and I've found

Hello.
I'm using FPC 2.2.2 on Xubuntu 8.10.
I need to reserve dynamic memory to store raw binary data. I tried the
next code:
fSize := aObject^.size;
GetMem (fData, fSize);
Move (aObject^.dat, fData, fSize);
Both "fData" and "dat" are untyped POINTER but the program returns an
