+% EEG_GLOBAL - declare global EEGLAB variables. These variables are
+%                used only as global by the main function EEGLAB,
+%                the function POP_REJMENU and the history EEGH function.
+%           
+% Global variables:
+%  EEG        - structure containing the current dataset
+%  ALLEEG     - array of structures containing all the loaded datasets
+%  CURRENTSET - index of the current dataset in the ALLEEG array
+%  LASTCOM    - most recent command run by EEGLAB
+%  ALLCOM     - cell array containing the EEGLAB session command history 
+%               See the history (h) function for more details.
