PInt64
Type
Pointer to an Int64 value System unit
  type PInt64 = ^Int64;
Description
The PInt64 type is a pointer to an Int64 value.
 
Pointer arithmetic, such as Inc, Dec can be used on it, for example to navigate a block of Int64 values, as in the example.

Dec Decrement an ordinal variable
Inc Increment an ordinal variable
Int64 A 64 bit sized integer - the largest in Delphi
 
Example code : Store 3 Int64 values in memory and navigate through them
