done at all on VMS systems, since they use file-versioning.]

Graphical User Interfaces
Several graphical user interfaces have been written for gnuplot and one for win32 is included in this
distribution. In addition, there is a Macintosh interface at
ftp://ftp.ee.gatech.edu/pub/mac/gnuplot
Also several X11 interfaces exist. One of them is called xgfe. It uses the Qt library and can be found on
http://www.flash.net/~ dmishee/xgfe/xgfe.html
In addition three Tcl/Tk located at the usual Tcl/Tk repositories exist.
Bruce Ravel (ravel@phys.washington.edu) has written a new version of gnuplot-mode for GNU emacs
and XEmacs. This version is based on the gnuplot.el file by Gershon Elber. While the gnuplot CVS
repository has its own copy the most recent version of this package is available from
http://feff.phys.washington.edu/~ ravel/software/gnuplot-mode/
Part IV
Bugs
Floating point exceptions (floating point number too large/small, divide by zero, etc.) may occasionally
be generated by user defined functions. Some of the demos in particular may cause numbers to exceed
the floating point range. Whether the system ignores such exceptions (in which case gnuplot labels the
corresponding point as undefined) or aborts gnuplot depends on the compiler/runtime environment.
The bessel functions do not work for complex arguments.
The gamma function does not work for complex arguments.
As of gnuplot version 3.7, all development has been done using ANSI C. With current operating system,
compiler, and library releases, the OS specific bugs documented in release 3.5, now relegated to old bugs,
may no longer be relevant.
Bugs reported since the current release as well as older ones may be located via the official distribution
site:

Please e-mail any bugs to bug-gnuplot mailing list (see Seeking-assistance (p. 13)).
43 Old bugs
There is a bug in the stdio library for old Sun operating systems (SunOS Sys4-3.2). The "%g" format
for ’printf’ sometimes incorrectly prints numbers (e.g., 200000.0 as "2"). Thus, tic mark labels may be
incorrect on a Sun4 version of gnuplot. A work-around is to rescale the data or use the set format
command to change the tic mark format to "%7.0f" or some other appropriate format. This appears to
have been fixed in SunOS 4.0.
Another bug: On a Sun3 under SunOS 4.0, and on Sun4’s under Sys4-3.2 and SunOS 4.0, the ’sscanf’
routine incorrectly parses "00 12" with the format "%f %f" and reads 0 and 0 instead of 0 and 12. This
