Bar Code Area Position (Bcap) - IBM 6400 Programmer's Reference Manual

Bar Code Command Set
Each structured field contains a two byte length field, then a two byte structured
field ID, and finally a data field.

Bar Code Area Position (BCAP)

The Bar Code Area Position Control structured field is the first structured field in
the DATA portion of the Write Bar Code Control command. This field defines the
origin and orientation of the bar code object relative to the reference coordinate
system. The format of the BCAP field is:

Figure 22 shows the BCAP field specifying the top left reference point, or origin,
for the bar code object, relative to the logical page. The figure shows 0-degree
and 90-degree rotations; the printers also support 180-degree and 270-degree
rotations.
