Table 26. Export List File Identifier
Bytes Name Description
0–10 Title Text “EXPORT LIST”
11 Delimiter Blank character
12–13 Version “01”
14 Blank Blank character
15–30 User Field This 16 byte field is not checked or used by the control
unit
31–79 Retained, Not
checked This field is not checked or used by the control unit
The format of the Export List File record is designed to allow for ease of use. It is
expected that a customer may manually input the needed information and the
format needs to be tolerant of the location of the fields in the record. Each list file
record contains up to two fields separated by a delimiter. The fields, “volser” and
“destination” must appear in that order, separated by a field delimiter. If the record
is not equal to 80 bytes, the record is not processed and a Status File record is
written with a status code of X'24'. The first 13 bytes or less of data from the record
as read is provided in the Status File record. If only one field is found in the record,
it is assumed that a blank destination is desired.
Table 27. Export List File Record
Name Description
Volser The volume serial number of a logical volume to be exported. The VTS will use six
characters to identify the volser, starting with the first non-blank character and continuing
until six non-blank characters have been found. Valid characters are A-Z, 0-9. The search for
six non-blank characters continues until a blank or delimiter comma character is found. Note:
If the volser found is not six characters, or contains non-valid characters, a Status File
record is written with a Status Code of X'1E' and with the first 13 bytes of the list record.
Field Delimiter Comma character required if a non-blank destination is specified.
Destination The destination for the logical volume. The control unit will use up to sixteen characters,
starting with the first non-blank character after the field delimiter and continuing through byte
71, for the destination name. Embedded blanks are allowed in the destination name. Any
characters in the record after the destination field are ignored. No validity checking is
performed on the name found. A blank destination is also valid; however, all characters after
the Volser or delimiter comma and throughout byte 71 must be blank.
User Field Bytes 72-79 of the 80 byte record are not used or checked by the VTS. This field may
contain line numbers for volume lists.
