As promised earlier, I have now visited my friend to see how
his Macs deal with it. On both machines, I first entered (in a
"terminal" window) the following:
$ eqn << EOT
.EQ
x = y + z
.EN
EOT
and got the usual slew of eqn output, and no error message.
Then I did essentially the same with groff:
$ groff -Tps -e -ms > ted.ps << EOT
.EQ
x = { Y + Z } over { A + B } times ( C + D )
.EN
EOT
and the resulting PostScript file had the equation nicely formatted
(and there were no error messages from the command).
He says he is using "OS X latest version (10.4.9) of Tiger",
(regularly updated), and when (in "terminal") I did
$ uname -a
I got: "Darwin 8.11.1, Kernel version 8.11.1" from October 2007.
The version of groff (and eqn, troff, grops) from "groff -version"
is 1.19.1 throughout.
The only thing not right which I saw was that when I did the -Tascii
version of the above (to see what would happen in the text window):
$ groff -Tascii -e -ms | less << EOT
.EQ
x = { Y + Z } over { A + B } times ( C + D )
.EN
EOT
the "Y + Z" was displayed several (approx 15) lines above the
x = ----- x (C + D)
A + B
but that may well be a separate issue (or may mean that I don't
know how to talk properly to a Mac!).
Hoping this helps!
Ted.
