Using LCDS Print Description Language
• Use of block and record constants in an appropriately
structured file (type F, FB, V, or VB) containing interleaved
graphics is supported. However, the actual delimiter
searching is suspended while an .IMG file is being read.
– For record delimiters, this means that delimiter searching
is suspended from the first record of graphic data until the
entire graphic has been read. Extraneous bytes at the end
of the last record are ignored. Record delimiter processing
resumes with the next record.
– For block delimiters, this means that the first byte of a
graphic must be the first data byte of a block and that the
first byte of data following the graphic must also be the
first byte of a block. Extraneous data in the last block
following the last byte specified by the IMG byte count is
ignored.
• Improved tape to disk processing time is obtained if the
graphic data portion of each record is an integer multiple of
512 bytes and begins at an even byte offset from the
beginning of the block. Processing of each graphic begins in
this mode. If a record is not a multiple of 512 bytes or does
not begin at an even byte offset from the beginning of the
block, the mode is terminated.
In this format, one or more graphics imaged on a physical page
are included in the data file immediately following the textual
data for that page. These graphics, if referenced, are processed
in Block mode. If not referenced, a page interleaved graphic is
skipped. The rules for page interleaved graphics are as follows:
• The graphics must occur immediately following the last text to
appear on the physical page.
• The four rules for document interleaved graphics apply to this
format also. Refer to the "Document Interleaved format"
section earlier in this chapter.
In this format, a report contains only graphics that will be imaged
one per page and an optional IMAGE DJDE preceding each
graphic. These graphics are processed as Block mode graphics.
The four rules for document interleaved graphics apply to this
format also. Refer to the "Document Interleaved format" section
earlier in this chapter.
NOTE: Block or record delimiters are not permitted.
