.SH NAME
vmur \- Work with z/VM spool file queues
.
.
.SH SYNOPSIS
.B vmur
.RI [ OPTIONS ]
.br
.B vmur
.IR vmur_command " [" command_options "] [" command_args ]
.
.
.
.SH DESCRIPTION
The \*v program allows to read, create, list, purge, or order files
on the z/VM spool files queues (RDR, PUN, and PRT).
\*v supports the following commands:
.RS 3
.TP 12
.RB "- " receive :
Read a file from the reader queue
.TP
.RB "- " punch :
Create a file on the punch queue
.TP
.RB "- " print :
Create a file on the print queue
.TP
.RB "- " list :
List one or all files on a spool file queue
.TP
.RB "- " purge :
Purge one or all files on a spool file queue
.TP
.RB "- " order :
Position a file at the top of a spool file queue
.
.RE
.PP
The \*v program requires the vmcp kernel module as prerequisite.
For the receive, punch, and print commands the vmur kernel module is also
required, and the corresponding z/VM virtual unit record devices
(in most cases 000c as reader, 000d as punch, and 000e as printer)
must be set online.
See
.BR chccwdev (8)
for setting devices online or offline.
.
.
.
.SH OPTIONS
.TP
.BR "\-h" " or " "\-\-help"
Print help information, then exit.
.TP
.BR "\-v" " or " "\-\-version"
Print version information, then exit.
.PP
All other options are command specific and will be discussed below in the
respective command context.
.

spoolid
[-O | outfile]
.PP
Minimum abbreviation: re
.PP
Use \fBreceive\fR when you want to read a file
from the z/VM reader queue.
The file to be read is identified by its spoolid,
a 4-digit decimal number.
Use the 'vmur list' command to display information
about files in the z/VM reader queue.
.SP
.SH receive options
.SP
The following command options are supported by \fBreceive\fR:

.IP "" 2
Specifies that the reader file to be received shall remain in the reader queue
after processing. If omitted, the reader file is purged.
.SP
.IP "" 0
\fB-C or --class\fR
.IP "" 2
Specifies the spool file class to match particular reader files. The class
value is a 1-character alphanumeric field whose values can be A through Z, 0
through 9, or asterisk (*).
If you omit this option, the asterisk (*) is used to receive files of any class.
.SP
.IP "" 0
\fB-d or --device\fR
.IP "" 2
Specifies the device node of the virtual reader device.
If omitted, /dev/vmrdr-0.0.000c is assumed.
.SP
.IP "" 0
\fB-t or --text\fR
.IP "" 2
Specifies that a text file requiring EBCDIC-to-ASCII conversion is to be
received. Character sets IBM037 and ISO-8859-1 are used for the conversion.
An ASCII line feed character (0x0a) is inserted for each 80-byte input
record read from the z/VM reader. Trailing EBCDIC blanks (0x40) in the
input records are stripped.
.SP
.IP "" 0
\fB-b or --blocked\fR

Specifies that the file is to be received using blocked mode.
As parameter for the -b option, the
hex codes of a separator byte and a padding byte have to be specified.
The parameter has the following format: 0xSS,0xPP
.br
All trailing padding bytes are
removed from the end of each record read from the virtual reader and
the separator byte is inserted afterwards.
The receive function's output can be piped to
.BR iconv (1)
using the appropriate character sets, for example:
.IP "" 2
# vmur re 7 -b 0x25,0x40 -O | iconv -f EBCDIC-US -t ISO-8859-1 > file
.SP
.IP "" 0
\fB-c or --convert\fR

.SP
.IP "" 0
\fBoutfile\fR
.IP "" 2
specifies the name of the output file to receive the
reader file's data.
.br
If both outfile and --stdout are omitted, name and type of the spool file

or print. The value is a 1- to 8-character value.
If the destination value has not been changed otherwise, for example, by a CP
SPOOL command, the default is OFF. OFF is the initial setting of the
destination value for virtual devices. Specify ANY to indicate that the
resulting spool file can be processed on any CP output device that meets other
selection criteria, regardless of the device's DEST setting.
.SP
.IP "" 0
\fB--dist\fR
.IP "" 2
Specifies the distribution code to be assigned to the spool files on this punch
or print. The distribution code, distcode, is a 1- to 8-character value and
appears on the separator page.
If OFF or an asterisk (*) is specified, the distribution code of the spool file
is reset to the distribution code in the system directory.
.SP
.IP "" 0
\fB-t or --text\fR
.IP "" 2
specifies to
punch or print the input file as text file, that is perform ASCII-to-EBCDIC
conversion (using character sets ISO-8859-1 and IBM037)
and pad each input line with trailing blanks to fill up the unit
device record. The unit device record length is 80 for a punch and 132
for a printer. If an input line length exceeds 80 or 132 for punch
or print, respectively, an error message is issued.
.SP

If a local user is specified (that is the --node option is omitted), the
user name is validated against the CP directory.
.br
The user option
is only valid, if the -r option has been specified.
If user is omitted, the data is transferred
to your own machine's reader.
.SP
.IP "" 0
\fB-n or --node\fR
.IP "" 2
Specifies the z/VM node ID of a remote z/VM system to which
the data is to be transferred. RSCS (Remote Spooling Communications
Subsystem) must be installed on the z/VM systems and
the specified node ID must be defined in the RSCS machine's configuration file.
The node option
is only valid, if the -u option has been specified.
If node is omitted, the data is transferred to the specified user
at your local z/VM system.
