I am a newbe too and I just asked and got this question answered, 
thanks to nice list people  (especially Brad and Emily). The command 
line:

EEG.data(71,:,: ) = EEG.data(66,:,: ) - EEG.data(65,:,: ); % EXG2 - EXG1

Gives me the difference between two channels, which for me is the 
horizontal eye movement.  In my case, channel 71 exists but was not 
used.  You can use the GUI Edit > Channel locations  to create a new 
channel if necessary.  I label it with the following command line:

EEG.chanlocs(71).labels='HEYE';  %but could do that with the GUI too.

I thank nice list people for helping me out.
