     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.


     KEYWORDS
          global, procedure, variable
