those menu commands are equivalent to the pl/sql sequence

spool -- specifies what file to write to
-- output is directed to file
spool out -- stops output to file

as other mentioned, you can also include column formatting
commands. another useful functionality you may want to investigate
is the trim-trailing-spaces command. trim-spool or something like that.
