Using Dynamic Job Descriptor Entries (DJDEs)
5-32 Using LCDS Print Description Language
• If the first record does not meet the requirements for a
label record, the preceding DJDE packet is printed on an
OPRINFO page with an error message indicating that no
label record was found. The system then proceeds to
process the data as variable text data.
• If the file cannot be created due to insufficient space on
the disk, the preceding DJDE packet is printed on an
OPRINFO page with an error message indicating that
there is not enough space on the disk to download the file.
The system then proceeds to read and discard the file.
2. If the destination file type is acceptable, the system obtains
the file size field from the label record and calculates the
extent of the file.
3. The file name and file type that appear in the label block are
converted to uppercase characters.
4. The system creates the file. If a file with the same name was
created as a result of earlier processing of this report, the
earlier copy of the file is replaced. Otherwise, a new copy is
created.
5. The system reads the file data records and stores them in the
file until the total extent of the file is spanned. The system
ignores record delimiters, and processes only the data
portion of the file.
•
If the FILE= () signaled the start of LPS labeled data, the
system assumes that more than one LPS labeled file may
be batched together, and checks for another label record
when it completes processing a file.
• If OPRINFO=YES and the file transfers are successfully
concluded, the file name and file type of each transferred
file are listed on the OPRINFO page with a brief indication
of whether the file was newly created or replaced an
existing file.
Delimited records
for LPS labeled
files
To prevent loss of data through trailing blank suppression
procedures on the host spooler, data records for LPS labeled
files must be delimited by appending an extra non-blank
character at the end of each record. The same non-blank
character must be used with all records processed during the file
processing period.
