SCRIBBLE(1) User Contributed Perl Documentation SCRIBBLE(1)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.
COPYRIGHT
Scribble was written by Brian White <bcwhite@pobox.com> and has been placed in the public domain (the only true "free").

unset(n) Tcl Built-In Commands unset(n)
__________________________________________________________________________________________________________________________________________________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
