First, log on to one of the Windows95 machines in any PUCC PC lab.
Under standard software, open a telnet session into omni.cc. In that window, define the environment variable "DISPLAY" as the name of the PC followed by a ":0". (In "ksh" this can be done by saying "typeset -x DISPLAY=mthw116pc6.cc.purdue.edu:0" where the "mthw116pc6" is replaced by the name of the PC.)
Under standard software, open an X-Win32 session. Once this is loaded onto the "start" bar, run X-Util32 from it. This will allow you to create a new session (e.g., "omni"). In the session, select "rsh", enter the machine (e.g., "omni.cc.purdue.edu"), your login, a command (e.g., "xterm") and click "ok".
Return to the omni telnet and type "xess" with some small number of rows and columns as parameters. (If you do not add the row/col params, the screen that is openned is very large and you must shrink and move the left and top sides until the sheet fits on the screen.)
The spreadsheet will pop up on the screen like any ordinary Win95 window.
To exit, simply close the spreadsheet from its top line menu or kill the xess procedure in the telnet window via Ctrl-C.
