1mDESCRIPTION0m
       This  command  is  ignored unless a Tcl procedure is being interpreted.
       If so then it declares the  given  4mvarname24m'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 4mvar-0m
       4mname24ms will refer to the global variable by the same name.

       Please note that this is done by  creating  local  variables  that  are
       linked to the global variables, and therefore that these variables will
       be listed by 1minfo locals 22mlike all other local variables.
