value (the next half word boundary).
Default: Device dependent; refer to the Accessing Files Programmer's
Guide for default record sizes.
device character array (optional)
Passes a string of ASCII characters terminating with any
nonalphanumeric excluding a slash (/) or period (.), designating the
device where the file is to reside. This parameter optionally specifies
density for tape files (;DEN= parameter) and/or environment files for
certain Hewlett-Packard laser printers (;ENV= parameter), a remote
environment (
node# ), and whether the device is to be allocated on a remote
machine (;VTERM).
Remote environments (
device = node #) cannot be specified for directories,
byte streams, or when the formal file designator specifies an escaped
pathname.
Syntax of the options available through the
device parameter are:
device = [ node #] [*** vol * volclassdevnamedevclass ]
[;DEN=
density ]
[;ENV=
printenv ]
[;VTERM]
node# remote environment option
Passes a remote node name to be accessed through remote
file access (RFA). The node name string must be followed
by a pound character (#) to delimit the string. The internal
format of the name must match that defined by the NS
3000/XL subsystem. Refer to the
Using NS3000/iX

.
Default: Local file access
* volume set option
Passing only an asterisk character (
* ) indicates to FOPEN
that the disk file can span all volumes in the volume set
bound to the group where the file resides. No set name is
actually passed. This option is applicable only at file
creation.
**vol volume name option
Passing a name, preceded by two asterisks (
** ), indicates
that the disk file is restricted to the volume whose name is
specified in
vol . The specified volume must reside within
the volume set bound to the group where the file resides.
This option is applicable only at file creation.
*volclass volume class option
Passing a name, preceded by one asterisk (
* ), indicates
