global(n) Tcl global(n)
_________________________________________________________________
NAME
global - Access global variables
SYNOPSIS
global varname ?varname ...?
_________________________________________________________________
DESCRIPTION
This command is ignored unless a Tcl procedure is being
interpreted. If so then it declares the given varname's to
be global variables rather than local ones. Global
variables are variables in the global namespace. For the
duration of the current procedure (and only while executing
in the current procedure), any reference to any of the
varnames will refer to the global variable by the same name.
SEE ALSO

KEYWORDS
