Start Addrs
The START ADRS field has the following format:
[
FRAME OFFSET
NUMBER
- - - - . L . _ - - - - - - I
FRAME NUMBER. This field specifies a frame number relative to which the
module will begin execution. This value is appropriate for insertion into the CS
register for program initiation.
OFFSET. This field specifies an offset rel.ative to the FRAME NUMBER that
defines the exact location of the first byte at which to begin execution. This value is
appropriate for insertion into the IP register for program initiation.

This record provides contiguous data, from which a portion of an 8086 memory
image may be constructed.
Frame Number
This field specifies a Frame Number relative to which the data bytes will be loaded.
Offset
This field specifies an offset relative to the FRAME NUMBER which defines the
location of the first data byte of the DAT field. Successive data bytes in the DAT
field occupy successively higher locations of memory. The value of OFFSET is con-
strained to be in the range 0 to 15 inclusive. If an OFFSET value greater than 15 is
desired, then an adjustment of the FRAME NUMBER should be done.
Dat
This field provides consecutive bytes of an 8086 memory image. The number of
DAT bytes is constrained only by the RECORD LENGTH field. The address of
each byte must be within the frame specified by FRAME NUMBER.

This record provides contiguous data, from which a portion of an 8086 memory
image may be constructed.
It
allows initialization of data segments and provides a
mechanism to reduce the size of object modules when there are repeated data to be
used to initialize a memory image.
