D.6 Machine int32 Info Record

There must be no more than one machine int32 info record per system file. Machine int32 info records must follow the variable records and precede the dictionary termination record.

int32 rec_type;

Record type. Always set to 7.

int32 subtype;

Record subtype. Always set to 3.

int32 size;

Size of each piece of data in the data part, in bytes. Always set to 4.

int32 count;

Number of pieces of data in the data part. Always set to 8.

int32 version_major;

PSPP major version number. In version x.y.z, this is x.

int32 version_minor;

PSPP minor version number. In version x.y.z, this is y.

int32 version_revision;

PSPP version revision number. In version x.y.z, this is z.

int32 machine_code;

Machine code. PSPP always set this field to value to -1, but other values may appear.

int32 floating_point_rep;

Floating point representation code. For IEEE 754 systems this is 1. IBM 370 sets this to 2, and DEC VAX E to 3.

int32 compression_code;

Compression code. Always set to 1.

int32 endianness;

Machine endianness. 1 indicates big-endian, 2 indicates little-endian.

int32 character_code;

Character code. 1 indicates EBCDIC, 2 indicates 7-bit ASCII, 3 indicates 8-bit ASCII, 4 indicates DEC Kanji.
