Thanks to Kit Baum, two packages have 
been updated on SSC. 

log2html
========

This is a package for Stata 8 which converts 
.smcl files (especially, but only, log files 
in SMCL) to HTML, written by Kit Baum, 
Bill Rising and myself. 

Yesterday, Friedrich Huebler raised an issue 
about splitting long lines, and Alan Riley 
explained how to tackle it. As promised, 
-log2html- now has an extra option -linesize()- 
and it also pays attention to the current linesize. 

npresent-nmissing 
================= 

This is a package, now for Stata 8, with two 
simple utilities to report concisely on the 
number of present (non-missing) or on the 
number of missing observations, counts being 
by default variable-by-variable or optionally 
observation-by-observation. Previous versions 
were published in STB-49 in 1999 and in STB-60 
in 2001. Those remain accessible for users of 
Stata <8. 

The Stata team at UCLA independently wrote this 
up as part of their excellent website at 
http://www.ats.ucla.edu/stat/stata/faq/nmissing.htm
However, that write-up refers to the original STB-49 
version and is now incomplete. 

The changes in this version include

1. support for -by varlist:- 

2. options for checking string values that contain 
spaces and/or periods (for various reasons, you 
might consider string values of " ", "   ", etc., 
or of ".", " . ", etc., to be substantively missing). 

3. improved documentation (using SMCL), mentioning
extended missing values .a to .z 

4. improved output (making use of new -list- 
where appropriate). 

As always, (most) users of Stata 8 will be 
able to install a package <pkgname> from 
SSC by 

. ssc inst <pkgname> 

or to overwrite an existing package by 

. ssc replace <pkgname>

<pkgname> in these cases is either 

log2html 

or 

npresent-nmissing

P.S. an update to the -tabsort- program is in the pipeline.
