.SH SYNOPSIS

\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. 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.
