The primary objective of the physical map is to ensure the
device independence in the applicaiton program. More
concretely, for input operations, the physical map defines
maximal data length and starting position of each field to
be read and allows BMS to interpret an input data stream.
For output operations, the physical map defines starting
position, length, field characteristic (Attibute Bytes) and
default data for each field, and allow BMS to add control
characters and commands for ouput in order to construcht an
ouput data stream.

The primary objective of the BMS symbolic map is to ensure
the device and format independec to the application
programs. Therefore, through the symbolic map, a layout
change in the formatted screen can be done independent of
the appllication program coding as long as the field name
and lenght remain same.
it is used by the application program, which issues a COBOL
COPY statement in order to include a symbolic map in the
program.
