# When I don't specify a block variable, @name is neglected and the output
# to a pdf file is (approximately):     "\nmore text"

# When I specify a block variable (ie. 't'), I can access the @name class variable
# for which the pdf file outputs:       "Andy\nmore text"

# How can I access the @name class varaible within the first example?
# I recognize this may be a problem of scope..... but I want to try to do this in the first example ..
