There's no particular order for either disabling the controls first or getting a bookmark. You can navigate through records and use bookmarks while controls are disabled. The important thing is you'd want to enable the controls after record navigation is complete. So you'd switch the first two statements in your example code.

A sample usage is: get a bookmark, disable the controls, loop through the records then return to the bookmark, enable the controls and free the bookmark. See the example code in the "Marking and Returning to Records" topic of the documentation.
