Command Definitions (FLUSHLOG-GETUSERMODE)
FOPEN
(such as tapes) used in a buffered mode, and is not applicable for files
representing interactive terminals.
This option must not specify a number of buffers whose combined size
exceeds the physical capacity of the file.
Default: 00010 (decimal 2)
4:7 Spooler copies
Indicates the number of copies of the file to be produced by the spooling
facility. The valid range is 0...127. This option is applicable to spooled
devices only. Specify this option for a file already opened (for example,
$STDLIST), this is the highest value supplied before the last FCLOSE takes
effect. The copies do not appear continuously if the system operator
intervenes or if a file of higher output priority is ready before the last copy
is complete.
Default: 0000001 (decimal 1)
0:4 Output priority
Indicate the output priority to be attached to the file for spooled output.
Applicable only to spooled devices. The valid range for this option is the
binary equivalent of 1..13. The output priority must be a number between
1 (lowest priority) and 13 (highest priority), inclusive. If a value less than
the current outfence set by the system operator is specified, file printing is
deferred until the operator raises the output priority of the file or lowers
the outfence. Specify this option for a file already opened (for example,
$STDLIST), the highest value supplied before the last FCLOSE takes effect.
Default: 1000 (decimal 8)
filesize 32-bit signed integer by value (optional)
Passes the maximum file capacity. For variable-length records, the
capacity is expressed in blocks (block =
recordsize * blockfactor ). For
fixed-length and undefined-length records, the capacity is expressed in
logical records:
• The maximum file size for ordinary, fixed length record files and
KSAM64 files is 128GB (137,438,953,472 bytes)
• The maximum file size for ordinary, byte stream record files is 2GB
(2,147,483,648 bytes)
• The maximum file size for other standard and KSAM XL files is
4,294,901,759 bytes (4 gigabytes less 64K bytes).
• The maximum file size for RIO, circular, and message files is dependent
upon both the record size and number of extents defined for the file:
• For circular and RIO files, a maximum file size of 500 megabytes is
possible if
recsize =256 bytes and numextent =32.
• For message files, a maximum file size of 500 megabytes is possible if
recsize =128 bytes and numextent =32.
