srec_formatted_binary \- Formatted Binary file format

.XX "srec_formatted_binary(5)" "Formatted Binary file format"
.\}
.SH DESCRIPTION
.\" ftp://ftp.dataio.com/main/Manuals/UniFam/Translation%20Formats.pdf
This is the PDP\[hy]11 paper tape format, described in the
DEC\[hy]11\[hy]GGPC\[hy]D PDP\[hy]11 "Paper Tape Software Programming
Handbook" 1972.
.PP
The file starts with a character sequence which appears as an arrow when
punched on 8\[hy]hole paper tape.
.RS
0x08, 0x1C, 0x2A, 0x49, 0x08, 0x00
.RE
.PP
Then follows a byte count, encoded big\[hy]endian in the low 4 bits of the
next 4 bytes. The high bits should be zero.
.PP
Then follows a 0xFF byte.
.PP
The data follows, as many bytes as specified in the header.
.PP
The trailer consists of the following bytes:
.RS
0x00, 0x00,
.RE
and then a 2\[hy]byte checksum (big\[hy]endian).
.PP
The alternate header sequence
.RS
0x08, 0x1C, 0x3E, 0x6B, 0x08, 0x00
.RE
is followed by an 8\[hy]nibble big\[hy]endian byte count.
.SS Size Multiplier
In general, binary data will expand in sized very little
when represented with this format.
