{\noindent Dear WEB Users:}

Several minor errors in WEAVE and in TANGLE have been reported and these
will all be corrected in due time.  You may wish to make the following
corrections to your copy now.

An error in the WEAVE program may lead to the omission of paragraph breaks
in some instances.  Changes should be made to modules 97 and 98 on page 51
of the printed documentation and corresponding corrections should be made
to the WEAVE.WEB taped source as noted below.

Line 1793 (module 97) which formerly read:\lbrk
begin if out\_buf[b]=" " then decr(b);\lbrk
\qquad \qquad should now read:\lbrk
begin if (out\_buf[b]=" ")and(b>0) then decr(b);

Lines 1811 through 1813 (module 98) which formerly read:\lbrk
{\rraggedd\1
$@$d finish\_line==
\qquad begin if (out\_ptr>0)or(limit=0) then flush\_buffer(out\_ptr);
\qquad end}

should be replaced by:\lbrk
{\rraggedd\1
$@$p procedure finish\_line; $\{$do this at the end of a line$\}$
\qquad label exit;
\qquad var k:0..buf\_size; $\{$index into {\tt |}buffer{\tt |}$\}$
\qquad begin if out\_ptr>0 then flush\_buffer(out\_ptr)
\qquad\qquad else begin for k:=0 to limit do 
\qquAd\qquad\qquad\qquad if (buffer[k]<>" ")and(buffer[k]<>tab\_marc) thenretuRn;
