- .BE

- .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.

- .SH KEYWORDS
- global, procedure, variable
