NAME

       scribble - popular crossword game similar to Scrabble(R)

SYNOPSIS

       scribble <level>

DESCRIPTION

       Scribble is a hybrid of crossword mentality, positional strategy, and a true test of your language mastery, similar to the well known
       Scrabble(R) game made by Hasbro.  You start with a board that serves for the placement for letter tiles.  On the board there are specific
       squares that when used can add to your score dramatically. These premium squares can double or triple letter values.  Some of these squares
       can even double or triple your word scores!  You must position yourself to grab the squares and block your opponent from spelling out a
       "killer" word.

   Options
       Scribble takes only one option: the play level.	This option is a number from 1 to 9 (inclusive) with higher numbers indicating a more
       difficult opponont.

       Scribble was written by Brian White <bcwhite@pobox.com> and has been placed in the public domain (the only true "free").

NAME

       unset - Delete variables

SYNOPSIS

       unset ?-nocomplain? ?--? ?name name name ...?
_________________________________________________________________

DESCRIPTION

       This  command removes one or more variables.  Each name is a variable name, specified in any of the ways acceptable to the set command.	If
       a name refers to an element of an array then that element is removed without affecting the rest of the array.  If a  name  consists  of	an
       array name with no parenthesized index, then the entire array is deleted.  The unset command returns an empty string as result.	If -nocom-
       plain is specified as the first argument, any possible errors are suppressed.  The option may not be abbreviated, in order to  disambiguate
       it  from possible variable names.  The option -- indicates the end of the options, and should be used if you wish to remove a variable with
       the same name as any of the options.  If an error occurs, any variables after the named one causing the error are not  deleted.	 An  error
       can  occur  when the named variable does not exist, or the name refers to an array element but the variable is a scalar, or the name refers
       to a variable in a non-existent namespace.

EXAMPLE

       Create an array containing a mapping from some numbers to their squares and remove the array elements for non-prime numbers:
	      array set squares {
		  1 1	 6 36
		  2 4	 7 49
		  3 9	 8 64
		  4 16	 9 81
		  5 25	10 100
	      }

	      puts "The squares are:"
	      parray squares

	      unset squares(1) squares(4) squares(6)
	      unset squares(8) squares(9) squares(10)

	      puts "The prime squares are:"
	      parray squares
