[comp.text.tex] Puzzlers for wannabe wizards

dhosek@euler.claremont.edu (Don Hosek) (05/11/91)

A couple puzzlers for those who think that they're TeX gurus.

Under what circumstances would {\char0} produce a character which
is NOT the character at position 0 in the current font? Assume
nothing strange with catcodes.

What is the difference between

\expandafter\def\expandafter\foo\expandafter{\bar}

and

\edef\foo{\bar}

dhosek@ymir.claremont.edu  | send a message to mailserv@ymir.claremont.edu 
Quixote Digital Typography | with a line saying send [DIRECTORY]FILENAME
714-625-0147               | where DIRECTORY is the FTP directory (sans 
---------------------------+ "anonymous") and FILENAME is the filename, e.g. 
"send [tex]00readme.txt". There is a list of files in each directory under the 
name 00files.txt. Binary files are not available by this technique.
