When you issue the HOSTEDIT
command from a SAS text editor window, the contents of the buffer
for that window are written to a temporary file in the
/tmp directory. A command invoking the host editor
that was specified in the EDITCMD system option is passed to the SAS
Session Manager. The SAS Session Manager issues the command to the
operating environment to invoke the editor for the temporary file.
The X display that is
used with the HOSTEDIT command is the same one that is used with your
SAS session.
