Many thanks for all the help.  Here is my new version-dependent initialization
cell, initialized at the top of the NB:

DisplayChannel=$DisplayFunction;
Joinedlistplot=PlotJoined->True;
If [$VersionNumber>=6.0, DisplayChannel=Print];  
If [$VersionNumber>=9.0&&$OperatingSystem=="MacOSX", 
    $CharacterEncoding="Unicode"];
If [$VersionNumber>=9.0, Joinedlistplot=Joined->True];

Not sure what happens to greeksymbol//InputForm under other OS, but
students do not need that filter.
