global(n)                                   Tcl Built-In Commands                                  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
       namespace(n), upvar(n), variable(n)
