\fBglobal \fIvarname \fR?\fIvarname ...\fR?

.SH DESCRIPTION
|
|
.PP
|
|
This command is ignored unless a Tcl procedure is being interpreted.
|
|
If so then it declares the given \fIvarname\fR'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 \fIvarname\fRs
|
|
will refer to the global variable by the same name.
