Double Quotes preservation while passing parameters.

I have the following sqlfile between the line of ###
##################################################
prompt &1
prompt &2
exit
##################################################

I called this file tmp.sql

So, if I pass this file double quoted parameters, the output doesn't preserve the double quotes. I need it to.

FOR EXAMPLE
SHELL> sqlplus -S galen/galen @tmp xxx "'hello goodbye'" xxx
hello goodbye

I need the output to show
SHELL> sqlplus -S galen/galen @tmp xxx "'hello goodbye'" xxx
"hello goodbye"

Is there a sqlplus option for this, or another way that anybody knows of?
