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.
