Command Definitions (FLUSHLOG-GETUSERMODE)
FOPEN
reading from a tape, the density of the tape overrides the
density value specified.
To specify density when writing to the tape file, use the
keyword ;DEN=.
Default: The highest density available on the device
opened
;ENV=
printenv printer environment option
Passes the name of a file that contains a printer
environment. Valid only for specified printers. If opening
an Hewlett-Packard 268x page printer file, an optional
printing environment can be specified for the job. The
printing environment is defined as all of the
characteristics of the printed page that are not part of the
data itself, including the page size, the margin width, the
character set, the orientation (horizontal or vertical), and
the name of the forms to use. If an environment file is not
specified, the file system selects a default printer
environment.
To specify a printer environment, assign the keyword
;ENV=, followed by the name of the environment file, to the
device parameter in the form ;ENV= printenv . Any
environment selected remains active until replaced by a
new environment or a call FCLOSE to close the printer.
Default: No printer environment file specified
;VTERM reverse VT option
Indicates that the specified device name is allocated on a
remote machine. Specify the remote location of a device
with the
device parameter as VTERM. Specify the remote
environment in the same open request, using either the
formaldesig parameter or the remote environment option
(see
node# above) of the device parameter. Reverse VT is
almost the same as a terminal opened up through remote
file access, except that no session is required on the remote
machine.
Default: No reverse VT
formmsg character array (optional)
Passes a forms message that can be used for sending messages (for
example, telling the system operator what type of paper to use in the line
printer) The message is a string of ASCII characters terminated by a
period. The maximum number of characters allowed is 49, including the
terminating period; more than 49 characters are truncated.
Used for tape label information if bit (6:1) of the
foption parameter is set.
The tape label information is formatted as follows:
