DISPLAY variables in Solaris
A Solaris Rational® DOORS® client can now run in batch
mode without a DISPLAY environment variable being
set. If the batch-mode DXL attempts to use the GUI and DISPLAY has
not been defined, Rational DOORS exits. If DISPLAY has
been defined, Rational DOORS attempts to connect to the
specified X display, even if the batch-mode DXL does not use a GUI.
As a result, DISPLAY must refer to a valid X display
that the user is authorized to connect to.
