In a certain two-argument definition, I wish that the second argument was
optional, i.e. if it's not there it is like it didn't exist at all in the
I don't understand well the use of \@getoptionalarg and \@optionalarg as
explained in eplain manual.
Can anybody please provide a clearer example of how I can make one of my two
arguments optional using \@getoptionalarg and \@optionalarg?
Thanks for any help
