Input for graphics
Named graphics may be input to the LPS through magnetic tape or
the online channel. They may be input either separately from or
interleaved with textual data. If input separately, they are recorded as
permanent disk files. If interleaved with textual data, they may or may
not be recorded as permanent disk files. (Refer to the “Processing
modes” section for a discussion of this operation.)

A graphic is typically incorporated into a document by a DJDE record
occurring with the data targeted for the same simplex or duplex page
on which the graphic appears. Additionally, a graphic may be
referenced in a form, so that use of the form automatically includes
the graphic.

Processing modes
A graphic is handled by the software in one of the following four
modes:
modes:
•
Batch
•
Block
•
Move
•
Random
The user selects the mode depending upon how the graphic is made
available for report processing, as well as user performance
requirements and disk resources.
available for report processing, as well as user performance
requirements and disk resources.
Random mode
In random mode, a graphic is obtained from a named disk file. This
occurs if the file already exists at the start of report processing or is
read from the report’s input data stream before the first record of the
report text is processed. In the latter case, each graphic is written to
the disk as a permanent IMG file. In random mode, the output
software reads the various graphics for a page from their individual
files into graphics memory.

software reads the various graphics for a page from their individual

Move mode
In move mode, a graphic is obtained from a named disk file (just as
in random mode), but the graphic is copied into the print file and used
as in block mode. This feature may be invoked by the GRAPHICS
command of the OUTPUT command. (Refer to the chapter “Print
format commands,” section “Specifying output parameters.”

Note:
Under some circumstances, move mode graphics are
overridden and treated as random mode. In particular, if for any page
there is exactly one graphic and that graphic is on a disk drive other
than the print file's disk drive, random mode is invoked.
