FOPEN
Bits (11:5)—Number of buffers.
Not meaningful for asynchronous devices. Data
transfers to and from terminals and printers are
always unbuffered.
Bits (4:7)—Number of copies.
For spooled output devices only, specifies the number of
copies of the entire file to be produced by the spooling
facility. You can specify number of copies for a file
already opened (for example, $STDLIST), in which case
the highest value supplied before the last FCLOSE
takes effect. The copies do not appear contiguously if
the System Operator intervenes or if a file of higher
output priority becomes READY before the last copy is
complete. These bits are ignored for nonspooled output
devices. The default value is 1.
Bits (0:4)—Output priority.
For spooled output devices only, specifies the output
priority to be attached to the file. This priority is used
to determine the order in which files are output when
several are waiting for the same device. Accepted
values are between 1 (lowest priority) and 13 (highest
priority) inclusive. If this value is less than the current
OUTFENCE set by the System Operator, file output is
deferred until the operator raises the output priority of
the file or lowers the OUTFENCE. You can specify
priority for a file already opened (for example,
$STDLIST), in which case the highest value supplied
before the last FCLOSE takes effect. These bits are
ignored for nonspooled output devices. The default
priority is 8.
filesize 32-bit signed integer by value (optional)
Not meaningful for asynchronous devices.
numextents 16-bit signed integer by value (optional)
Not meaningful for asynchronous devices.
initialloc 16-bit signed integer by value (optional)
Not meaningful for asynchronous devices.
filecode 16-bit signed integer by value (optional)
Not meaningful for asynchronous devices.
