Sorry - I thought I'd included enough to justify my questions. Here's a 
full source file, which produces the problem, minus all methods and 
classes not relevant to the immediate problem -

# SetNet.rb

def main
  # Set up logging
  run_log = Toggle_log.new( 'logfile.txt' )
  run_log.open
  @log = run_log.log
  logging_now = run_log.lgg 
  # [...]
end

class Toggle_log 
  attr_accessor :log, :lgg
  def initialize( logFileName )
    @logFileName = logFileName
  end
 
  def open 
    #create log file
    log_main = File.open( @logFileName, File::WRONLY | File::APPEND )
    @log = Logger.new( log_main )
    @log.datetime_format = "%Y-%m-%d %H:%M:%S"
    @lgg = true
 
    # set logging level
    @log.level = Logger::INFO # I.e., only INFO level and above will be 
logged
    @log.info( '===== START logging' ) # just a program place indicator
    puts '> logging started, at INFO level'
  end

  def close
    @log.info( '===== STOP logging' ) # just a program place indicator
    puts '> logging stopped'
    @log.close
    @lgg = false
  end
end

class SetLogLevel
  def initialize( log )
    @log = log
  end
  puts "> logging level options - from most to least grave -"
  puts "> 5 = FATAL | 4 = ERROR | 3 = WARN | 2 = INFO | 1 - DEBUG | 0 = off"
  puts "> enter choice (x - exit logging level entry)"
  while true
    opt = Readline::readline( ":: " )
    case opt
    when 'x' then break # exit
    when '5' then
      @log.warn( 'logging level changed to FATAL' )
      @log.level = Logger::FATAL
      puts '> logging level now FATAL'
    break
    when '4' then
      @log.warn( 'logging level changed to ERROR' )
      @log.level = Logger::ERROR
      puts '> logging level now ERROR'
    break
    when '3' then
      @log.warn( 'logging level changed to WARN' )
      @log.level = Logger::WARN
      puts '> logging level now WARN'
    break
    when '2' then
      @log.warn( 'logging level changed to INFO' )
      @log.level = Logger::INFO
      puts '> logging level now INFO'
    break
    when '1' then
      @log.warn( 'logging level changed to DEBUG' )
      @log.level = Logger::DEBUG
      puts '> logging level now DEBUG'
    break
    when '0' then
      @log.warn( 'logging level changed to OFF; logging closed' )
      @log.close
      puts '> logging stopped'
    break
    else puts "> '"+opt+"' - ? [#2]"
    end
  end
end
