One more GDB open mode is connected with using the so-called history list containing the names of several last opened GDB. This list is included into GDB menu and is located at the bottom of this menu. Selection of one name from this list causes corresponding GDB opening.
At figure 5-4 the main window with opened GDB menu is shown. The menu contains a list of four names of GDB that were opened recently.
Figure 5-4. GDB menu with history list
Beside GDB name the history list has indication to the used open mode of the present GDB. That is why GDB “City” appears three times in the list: only the name (which corresponds to opening in standard mode), with a mark (sr), that is, in shared access mode (s) only for reading (r), and with a mark (s), that is, in shared access mode for reading and writing. So, selection of any of these lines will cause GDB “City” opening in the indicated mode. Besides, in the history list there is GDB “Demo” with a mark (f), that is, the one opened in the mode with the change file.
