Subject: Using a variable as a method name?

Hello,

I need a bit of help understanding how to use a
variable as a name for a method call.  Forgive me
trying to explains this, I am new at all this.  In the
code listed, I am tring to set the debugging level of
the Logger class, however, the variable in question is
not being sustituted prior to interpreting the method
call.

when "--debug"
  if($DEBUG_LEVELS.include?(arg))
    mylog.level = Logger::arg
                  ^^^^^^^^^^^       
  else
    puts "Debug level can be one of: DEBUG, INFO,
WARN, or ERROR"
    dis_help
  end

This causes Ruby to spit out that there is no method
called arg which is correct.  So how do I get arg to
be substituted to the value rather than the var name? 
I tried dereferencing and using the it within a string
(okay, a dumb idea).  Any way, any help will be much
appreciated!

TIA!
Phy
