Description

You use the Next Volume service when you want to proceed to the next volume in the set before the end of the current volume (EOV label) is reached on input, or before the end-of-tape (EOT) mark is reached on output. RMS positions your process to the first file section on the next volume. File sections occur when a file is written on more than one volume, the portion of the file on each of the volumes constituting a file section.
When you perform a Next Volume service for input files, RMS responds as follows:

If the current volume is the last volume of the set, RMS reports end-of-file information.
If another file section exists, the next volume is mounted. When necessary, the current volume is rewound and a request to mount the next volume is issued to the operator.
The header label (HDR1) of the file section on the newly mounted volume is read. If this is not the volume being sought, the operator is requested to mount the correct volume.

When you perform a Next Volume service for output files, the following sequence occurs:

The file section on the current volume is closed with the appropriate end-of-volume labels, and the volume is rewound.
The next volume is mounted.
A file with the same file name and the next higher file section number is opened for output, and processing continues.

If your program is operating asynchronously, it must wait for any I/O activity on this volume to complete before issuing a Next Volume service.
The Next Volume service performs a Flush service for write-accessed volumes (see $FLUSH), thus writing the I/O buffers on the current volume before creating the next file section. If this is an input-only file, then all records currently contained in the I/O buffers are lost, and the next Get service returns the first record on the next volume.
The Next Volume service is not supported for DECnet for OpenVMS operations on files between two OpenVMS systems.
Table RMS-47 lists the control block fields read as input and written as output by the Next Volume service. For additional information on the fields accessed by this service, see Part 2.

$OPEN

The Open service makes an existing file available for processing by your program. The Open service specifies the type of record access to be used and determines whether the file can be shared. The Open service also performs an implicit Display service.

mechanism: by value

The value is returned in symbolic offset FAB$L_STS. Symbolic offset FAB$L_STV may contain additional status information.

Arguments

type: longword (unsigned)

access: modify

mechanism: by reference

FAB control block whose contents are to be used as indirect arguments for the Open service call. The fab argument is the address of the FAB control block.
err

OpenVMS usage: ast_procedure

type: procedure value

mechanism: by reference

AST-level success completion routine that the service invokes if the operation is successful. The suc argument is the address of the entry mask of this user-written completion routine.

Description

You must open a file to perform any record operations and most file operations. If any XABs are chained to the FAB, RMS places the attribute values in the fields of the appropriate XAB. If you specify a NAM or NAML block in the FAB, the contents of the device, directory, and file identification fields can be used with the open-by-NAM-block option to open the file. The NAM or NAML block fields are filled in with auxiliary file specification information.
Table RMS-49 lists the FAB and XAB control block fields read as input by the Open service. For additional information on the fields accessed by this service, see Part 2.
