The initial workspace and the default directory can be specified on the commandline as -w file.wks and -d dir, respectively.
Upon startup of the X11 version of XLISP-STAT the system merges resources found in file /usr/lib/X11/app-defaults/Xlisp
then ones found in the file Xlisp in the directory named by the environment variable XAPPLRESDIR, and finally the resources of the display. Resources can thus be specified in all three places, with the display's resources having highest precedence.
The functions popen and pclose from winterp have been added to the UNIX version to allow streams connected to processes to be created.
The interface to these functions may change.
