Yes, pointers are one of the harder things about programming. I'll have some links for you:

Ok, I'll breifly explain them:
All your variables are stored in RAM memory. Pointers are also stored there, but they point to another location in RAM. They don't contain value's like 6 or "abc", but memory adresses.
A quick example:
Hope that helps.Code://Make a new pointer type that points to integers (not sure if this allready exists) type pinteger = ^integer; var v, w: integer; p: pinteger; begin v := 100; w := 50; p := @v; //the value of p is now the memory location of v showmessage( IntToStr( p^ ) ); //Output: 100 (^ means: show us what is stored at this memory location) v := v + 10; showmessage( IntToStr( p^ ) ); //Output: 110 p := @w; //Let p point to w now showmessage( IntToStr( p^ ) ); //output 40 p := nil; //NIL means "points to nothing" showmessage( IntToStr( p^ ) ); //gives an error end;
