the result of that evaluation.

If \fIlevel\fR is an integer then
it gives a distance (up the procedure calling stack) to move before
executing the command.  If \fIlevel\fR consists of \fB#\fR followed by
a number then the number gives an absolute level number.  If \fIlevel\fR
is omitted then it defaults to \fB1\fR.  \fILevel\fR cannot be
defaulted if the first \fIcommand\fR argument starts with a digit or \fB#\fR.
.PP
For example, suppose that procedure \fBa\fR was invoked
from top-level, and that it called \fBb\fR, and that \fBb\fR called \fBc\fR.
Suppose that \fBc\fR invokes the \fBuplevel\fR command.  If \fIlevel\fR
is \fB1\fR or \fB#2\fR  or omitted, then the command will be executed
in the variable context of \fBb\fR.  If \fIlevel\fR is \fB2\fR or \fB#1\fR
then the command will be executed in the variable context of \fBa\fR.
