        !            36: .PP
        !            37: This is a utility procedure used by many of the Tcl commands.
        !            38: It changes the value of variable \fIvarName\fR in
        !            39: interpreter \fIinterp\fR, such that future calls to \fBTcl_GetVar\fR
        !            40: will return \fInewValue\fR as the value of \fIvarName\fR.
        !            41: \fBTcl_SetVar\fR uses the same rules for selecting
        !            42: a global or local variable as \fBTcl_GetVar\fR.  If \fIvarName\fR
        !            43: doesn't already exist, then a new variable is created.
        !            44: \fBTcl_SetVar\fR copies both \fIvarName\fR and \fInewValue\fR into
        !            45: its own private storage, so the caller may change the contents
        !            46: of these strings after \fBTcl_SetVar\fR returns without affecting
        !            47: the variable's value.
