+The "\relax" test is how LaTeX does it, but so many meaningful
+commands are \let equal to \relax, it is a very unreliable method.
+For example, in LaTeX, you can foolishly do: \newcommand{\protect}{}
+and disaster will follow.
+
+I have used various bizzare names (\Und@rfined, e.g.) but I now just
+use \undefined. If you define it, things will break anyway, so just
+trust it.
+
+For a version that *can* be skipped in conditionals, there must be
+an obvious fundamental \if__ command, so:

+\def\undefined#1{..\fi\expandafter\ifx\csname#1\endcsname\relax}

+Use: \if\undefined{this}use \this \else \def\this{} \fi
+
+(None of this is news to Karl, but I thought I would (b)elaborate.)

+Subject: LaTeX2e compatibility problem
+
+We have encountered a problem with the way LaTeXe treats the UK currency
+symbol (called up by the \pounds{} macro) compared to
+LaTeX 2.09. It appears that LaTeX2e, even in 2.09 compatibility mode,
+no longer uses the italicised dollar symbol in the 'cmti' font but
+invokes a symbol from the 'cmu' font instead. This might go unnoticed
+if one has such a font raster image installed. If not, the result may
+be some mild grumblings from a device driver when one comes to view or
+print it and a blank space on output if the driver doesn't make fonts on
+the fly.
+
+So, I guess my question(s) is/are: 'Is it a bug or a feature and are there any
+other similar, related, differences one might encounter?'

+
+a) color previewers for DOS. there are no
+previewers of which I am aware that implement
+the full spec of the LaTeX2e colour package. I
+suggest using a dvi to PostScript, and then
+GhostScript. PCTeX#s dvi to PS is partially
+compatible with the colour package, but doesnt
+implement everything
+
+b) psview. i use this GhostScript addon every
+day. the batch files in the archive are for 4DOS,
+since they emanate from the 4AllTeX people. I
+suggest reading the file ps_view.ps for
+instructions. I append a suitable DOS batch file
+for those with ansi.sys loaded. the paths will
+need editing

+Subject: Macros to upcase/lowercase words with dotless i.
+
+I wonder to know a macro to upcase words with dotless i. By the way, this
+necessity arose when I used the package portuges.sty in LaTeX2e.
+
+Portuguese is a language that, frequently, uses the sequence \'\i{}. So,
+for example with "book" style, the chapter title is automatically upcased
+and put in the running head, but all sequences \'\i{} remain as they are,
+instead of the correct \'I. The reason is that the TeX primitive
+\uppercase don't do this job.
+
+Thanks in advance.

+Subject: Re: email/path/http macros
+
+I had an idea for a good way to allow linebreaks in email addresses
+and such: typeset in math mode and let punctuation characters be
+relations and binary operators. This even gives good breakpoints
+in "http://whatever" --> http: // whatever
+
+I put together the macros, with no real documentation yet, but I would
+like some opinions before finalizing them. Would anyone like to do
+a test run? I have some specific questions:
+
+ - How is my default list of punctuation characters?
+ - Are there inappropriate breaks/non-breaks?
+ - Should I make it easy to define different macros with different
+ punctuation lists? (despite the added complexity)
+ - What should the main macro be called? I used "\email", but that
+ is probably in heavy use already.
+ - LaTex2e options or plain TeX compatibility?
+
+So send me email, and I'll send you \email!
