{
{   The purpose of this request is to reposition to the beginning}
{ of the information on the current volume. This request is intended for}
{ files which span volumes. If the file resides on a single volume, the}
{ effect of this request is the same as amp$rewind. This request has meaning}
{ only for files opened with amc$record or amc$physical access_level.}
{   Any modified data residing in memory is flushed to the current volume.}
{ Any outstanding no_wait requests are completed before the repositioning}
{ is attempted.}
{   If the label_type is amc$labelled and the preceding operation was an}
{ output, a standard ANSI EOF label group is written.}
{   If the label_type is amc$unlabelled and the preceding operation was an}
{ output, the file is terminated with two tapemarks.}
{   The result of this request is that the current volume is rewound}
{ and positioned beyond the label group at the beginning of the volume,}
{ if such a label group exists.}
{   If a label_exit_procedure was specified, control will be passed to this}
{ procedure if labels matching the label_options attribute are encountered}
{ during this process.}

{ FILE_IDENTIFIER: (input) This parameter specifies the file access

{ WAIT: (input) This parameter specifies the action to be taken
{       if the rewind_volume can not be completed without causing
{       a physical I/O operation to be submitted.
