SPECIFYING DYNAMIC JOB DESCRIPTOR ENTRIES (DJDES)
Card-image file processing
8-74
The FILE parameter is checked for valid parameters, and an
appropriate amount of disk space is made available for the file.
•
If the destination file type is not acceptable for a card-image file,
the preceding DJDE packet is printed on an OPRINFO page
together with the message:
FILE PROCESSING ERROR - ILLEGAL DESTINATION
FILE TYPE.
Input then proceeds to read and discard the extent of the file.
•
If the file name is improperly specified, the preceding DJDE
packet is printed on an OPRINFO page together with the
message:
FILE PROCESSING ERROR - INVALID DESTINATION
FILE NAME.
Input then proceeds to process the data as variable text data.
•
If more card-image records are read than are predicted by the
parameter specifying the maximum number of card images, the
extra records are read and discarded, and the preceding DJDE
packet is printed on an OPRINFO page together with the
message:
FILE xxx.yyy OVERFLOW - EXCESS CARD-IMAGES
LOST.
•
If the file cannot be created due to insufficient space on the
disk, the preceding DJDE packet is printed on an OPRINFO
page together with the message:
NO SPACE ON DISK FOR FILE xxx.yyy.
Input then proceeds to read and discard the extent of the file.
When a card-image file record is read, the PCC byte is ignored. Block
and record delimiters (if any) are used to determine record length.
Records with a length greater than 80 bytes are truncated to 80
bytes; records with a length less than 80 bytes are padded with ASCII
blanks to 80 bytes. Character translation may be performed,
depending on the JDE in effect.
Sequence numbers are not inserted into the records prior to storing,
so the file must be retrieved by MERGE prior to editing in order to
insert valid sequence numbers.
Any DJDE record serves to terminate card-image record processing
for the file being downloaded.
•
If a DJDE record is encountered and one or more card-image
records have been written in the file, the file is truncated to an
appropriate size and closed. If OPRINFO=YES, the message:
FILE xxx.yyy CREATED
is listed on an OPRINFO page.
•
If a DJDE record is encountered before any card-image records
have been filed, the preceding DJDE packet is printed on an
OPRINFO page together with the message:
FILE xxx.yyy ERROR - NO CARD IMAGE DATA
and the null file is deleted.
