xmath is xmath.rt, not rtbin/xmath (yes, Henry, I know you've already
reported this one).
The help file is very obviously the info file (by this I mean a file
in "info" format) for gnuplot. If xmath is a modified gnuplot, it
shouldn't be called our own program; if it is new, it shouldn't be
using gnuplot's documentation.
"Help" probably shouldn't display the info node headers and "*menu"
and "*note" items. It seems to assume a 24-line screen. At least, it
is doing so here in my 45-line window.
It seems to have some difficulty in dealing with some exposure events.
I pulled up a second window, moved window xmath(0) in front of
xmath(1), and selected close-window in xmath(0). The graph in
xmath(1) did not redisplay itself until I pushed it behind another
window and brought it forward again.
It might be convenient to add inverse hyperbolic functions to the
repertoire of xmath. They are fairly straightforward given
exponentiation and logarithms; see your handy CRC handbook for
details. (There was a question on inverse sinh in olc this evening.)
