NAME

       srec_formatted_binary - Formatted Binary file format

DESCRIPTION

       This  is  the  PDP‐11 paper tape format, described in the DEC‐11‐GGPC‐D PDP‐11 "Paper Tape
       Software Programming Handbook" 1972.

       The file starts with a character sequence which appears as an arrow when punched on 8‐hole
       paper tape.
              0x08, 0x1C, 0x2A, 0x49, 0x08, 0x00

       Then  follows a byte count, encoded big‐endian in the low 4 bits of the next 4 bytes.  The
       high bits should be zero.

       Then follows a 0xFF byte.

       The data follows, as many bytes as specified in the header.

       The trailer consists of the following bytes:
              0x00, 0x00,
       and then a 2‐byte checksum (big‐endian).

       The alternate header sequence
              0x08, 0x1C, 0x3E, 0x6B, 0x08, 0x00
       is followed by an 8‐nibble big‐endian byte count.

   Size Multiplier
       In general, binary data will expand in  sized  very  little  when  represented  with  this
       format.

EXAMPLE

       Here is a hex dump of a formatted binary file containing the data "Hello, World!".
              0000: 08 1C 2A 49 08 00 00 00  ..*I....
              0008: 00 0E FF 48 65 6C 6C 6F  ...Hello
              0010: 2C 20 57 6F 72 6C 64 21  , World!
              0018: 0A 00 00 04 73           ....s
