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. 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.
