buy or sell, my lord? 
    starts with 1000 units 
    answer has form:  king buy 20 or king sell 30  
   1% king buy 20
    decision was buy 20, total was 1020.0 
 
   advisor:  new situation 
   need 10 liters of grain.
   need 60 hectares of land.
   predict rain.
   subjects from census 5000. 

    advisor: buy or sell, my lord? 
    2% king sell 500
    decision was sell 500, total was 520.0 
 
    advisor:  new situation 
    need 10 liters of grain.

    advisor: buy or sell, my lord? 

      Commands from the king on the TCL console  
      or commands in the king entry field (canvas gui)
      vary on versions, but here are some samples.
      initial land is 1000 barleyfields
      initial barley is 1000 measures
      king buy 22
      king sell 100
       else 
      king buy 100 land
      king sell 33 land
      king buy 222 barley
      king sell 33 barley
      conditions for winner are very liberal.

      kingdom starts with 1000 units land 
      initial barley is 1000 measures <for palace>
      king's answer has lower case form: 
      example >>   king buy 20 land 
      example >>   king sell 30 land  
      example >>   king buy 33 barley 
      example >>   king sell 11 barley 
      example >>   for new game, enter command reset 1 

    pseudocode: game is halted after 5 trials, count > 5,
    and estimate if (winner) conditions prevail.
    pseudocode:  if barleyfields > 500 , winner declared
    pseudocode:  if barley  > 500 winner declared
    pseudocode:  clear resets counter to zero
    pseudocode:  clear zeros king & advisor entry fields, 
    pseudocode:  & zeros canvas

      Refer to [A simple version of Eliza].    
      Console:  king sell 11 barley 
     1% ::Talk::replyto { barley }
      advisor says : Shall we continue? 
     2% ::Talk::replyto { king sell barley }
       advisor says worried about total  barleyfields. ? 
     3% ::Talk::replyto { king sell 11 barley }
       advisor says : worried about total barleyfields. ? 
     4% king sell 11 barley
     decision was sell 11, total was   land 1000, barley 989.0
