Version 4 of Lotto 2

Updated 2005-06-04 21:09:53

HJG This variation of Lotto by RS writes a log of each drawing to the console, compares the drawing to the tip, and counts the matching numbers.

Todo: * clicking on the numbers should set/reset the numbers in the tip * use a text-widget or listview for the log * Statistics

 #------------------ Generally useful functions:

  proc iota1 n {
     set res {}
     for {set i 1} {$i<=$n} {incr i} {lappend res $i}
     set res
  proc ldraw _list {
     upvar 1 $_list list
     set pos [expr {int(rand()*[llength $list])}]
     K [lindex $list $pos] [set list [lreplace $list $pos $pos]]
  proc K {a b} {set a}


  lappend MyTip  1 8 11 15 47 49  16
  set     DrawNr 0
  catch {console show}
  puts "Lotto"
  puts "MyTip: $MyTip"
