srec_dec_binary(5)	       File Formats Manual	      srec_dec_binary(5)

NAME
     srec_dec_binary - DEC Binary (XXDP) file format

DESCRIPTION
     The  DEC Binary (XXDP) format was used on the PDP 11 series machines.  This
     is a binary format, and is not readable or editable  with	a  text  editor.
     The file consists of records of the form
		+------+--------+---------+------------+----------+
		| type | length | address | ...data... | checksum |
		+------+--------+---------+------------+----------+
     The field are defined as follows:

     type    Two byte little-endian value.  Must always be 1.

     length  Two  byte	little-endian value.  This is the number of bytes in the
	     data, plus six.

     address
	     Two byte little-endian value.  This is  the  load	address  of  the
	     data.

     data    The data is simple raw bytes.  There are (length-6) of them.

     checksum
	     The  checcksum  is a single byte.	It is the negative of the simple
	     summ of all the header and data bytes.

     If the record length is exactly 6 (i.e. no data),	this  is  the  execution
     start address record, indicating the transfer address.

     In  addition  there  may  be NUL padding characters between records.  It is
     common for records to be padded so that they start on even byte boundaries.
     In the days of paper tape, it was common for the file to have many  leading
     NULs, to generate blank leader on the tape.

   Size Multiplier
     In  general,  raw	binary	data  will expand in sized by approximately 1.03
     times when represented with this format.
