- DESCRIPTION
- This command is ignored unless a Tcl procedure is being
- interpreted. If so then it declares the given _v_a_r_n_a_m_e's to
- be global variables rather than local ones. For the dura-
- tion of the current procedure (and only while executing in
- the current procedure), any reference to any of the _v_a_r_n_a_m_es
- will refer to the global variable by the same name.
