Allocates a bookmark for the current cursor position in the dataset.

function GetBookmark: TBookmark; virtual;

Call GetBookmark to establish a bookmark for the active record in the dataset. Establishing a bookmark for a record enables an application to return to that record in the dataset at any time while the bookmark exists.

GetBookmark requires that a variable of type TBookmark already be declared in the application. Use GetBookmark to assign the variable a value that can be referenced by subsequent calls to GotoBookmark and FreeBookmark.

Applications that create bookmarks with GetBookmark should subsequently release the system resource allocated to them by calling FreeBookmark when the bookmarks are no longer needed.
