***Preface***
----
[gold] 10/08/2020. Here is some  code for king_strategy_game.tcl. There is a post on wiki asking for a TCL version of a text and strategy game, originally in basic language. See [Ideas for Projects in Tcl/Tk].  
----
***Introduction*** 
A strategy game can be cobbled from older scraps of [Iching_Fortunes] code. Using the Iching code, this page presents a trial console version for testing the concept in a console version  The Iching has a good handle on the actions of an ancient kingdom, though in a random scattered pattern. The elements in most adventure games are random generators, castles, tiled game boards, mazes, wildcards, gamepieces, and strategy situation. The random pick algorithm was posted by Suchenworth [RS] on [Horseracing in Tcl]. Another source of randomness was [A funny cookbook].

----
**Pseudocode Section**  
----
**Session from trial console script**
======
    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.
    need 100 hectares of land.
    predict cold.
    subjects from census 3000. 

    advisor: buy or sell, my lord? 
======
----

**Sample commands from King**
======
      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.
======
----
**Pseudocode for Example Commands from King**
----
======
      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 for Endgame **

======
    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
======
----   
** Dialog from Trial Merge of  Eliza namespace **
======
      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 
======

***Testcases Section***  

In planning any software, it is advisable to gather a number of testcases to check the results of the program. The math for the testcases can be checked by pasting statements in the TCL console. Aside from the TCL calculator display, when one presses the report button on the calculator, one will have console show access to the   capacity  functions (subroutines).
