SYNOPSISglobal 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 var‐
names will refer to the global variable by the same name.
