Description:
Establish the
X client-server connection. The display name specifies the node on which the server is
running. Most applications will use the default device in which case the logical argument
USEDEF should be set to true and the display name is ignored. An error handler is established
which reports errors via EMS. This routine has to be called before any of the other GWM
FORTRAN interface routines. The connection is terminated by the routine GWM_CLOSE.
Invocation
CALL GWM_OPEN( DISPLY, USEDEF, STATUS )
Arguments
DISPLY =
CHARACTER()
(Given)
Display name specifying the network node name and
display number of the workstation. The format of the name will be
"hostname:number.screen"
if the transport mechanism is TCP/IP or
"hostname::number.screen"
if the transport mechanism is DECNET. The "hostname" is the name of the host machine to which the
display is physically connected. The "number" is the number of the server on the host machine. A
single CPU can have one or more servers which are usually numbered starting with zero. On a
multiple-screen workstation the optional "screen" number indicates the screen to use. Examples are
"cpu:0", "cpu::0", "cpu:0.1" or "cpu::0.1". If USEDEF is true the display name is ignored.
USEDEF =
LOGICAL (Given)
If true use the default display, otherwise use the display specified by
the DISPLY argument.
STATUS = INTEGER (Given and Returned)
The global status.
