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.
