The man page for eqn states that "All text that is neither between delimiters
nor between .EQ and .EN is passed through untouched." However, when I run the
following through eqn,
.EQ
delim $$
.EN
.LP
$A$ \f2or $B$ or C.
it appears that eqn treats the entire line as an equation and creates the long
string \*(11 given by
\x'0'\f2\s10A\s10\f1 \f2or \x'0'\f2\s10B\s10\f1 or C.
In the midst of all the font changes introduced by eqn, the fact
that the font was changed to italics just before the word "or" is
completely missed. After the $B$ is processed, the font is reset to what it
was just after the .LP command, i.e. roman font. Thus, the words "or C." appear
in roman font, rather in italic font, as I expected. Is this a bug? or is it a
feature? (We have a 4.2bsd system.)simmons@applga.uucp (Steve Simmons) (06/10/88)
Consider the following two scripts:
OK Buggy
#!/bin/csh | #!/bin/csh
if ( 1 ) then | if ( 0 ) then
cat << HERE | cat << HERE
else | else
HERE | HERE
else | else
echo There | echo There
endif | endif
Executing OK is fine -- it echos 'else'. Executing Buggy gives an error
HERE: Command not found.
It appears that in Buggy it is disregarding the here document *even though
it is syntactically correct*.
The Bourne and Korn shell equivalents to this script work fine, ie, buggy.sh
echos 'There'. Bug in the C shell? Or a wierdness of syntax that I can
use to convince people Korn is better? :-)

Oh, BTW, in my personal opinion, I would say that the Korn shell is "somewhat" better than the C shell.
