Next: Long String Missing Values Record, Previous: Character Encoding Record, Up: System File Format [Contents][Index]
This record, if present, specifies value labels for long string variables.
/* Header. */
int32 rec_type;
int32 subtype;
int32 size;
int32 count;
/* Repeated up to exactly count
bytes. */
int32 var_name_len;
char var_name[];
int32 var_width;
int32 n_labels;
long_string_label labels[];
int32 rec_type;
Record type. Always set to 7.
int32 subtype;
Record subtype. Always set to 21.
int32 size;
Always set to 1.
int32 count;
The number of bytes following the header until the next header.
int32 var_name_len;
char var_name[];
The number of bytes in the name of the variable that has long string
value labels, plus the variable name itself, which consists of exactly
var_name_len
bytes. The variable name is not padded to any
particular boundary, nor is it null-terminated.
int32 var_width;
The width of the variable, in bytes, which will be between 9 and 32767.
int32 n_labels;
long_string_label labels[];
The long string labels themselves. The labels
array contains
exactly n_labels
elements, each of which has the following
substructure:
int32 value_len; char value[]; int32 label_len; char label[];
int32 value_len;
char value[];
The string value being labeled. value_len
is the number of
bytes in value
; it is equal to var_width
. The
value
array is not padded or null-terminated.
int32 label_len;
char label[];
The label for the string value. label_len
, which must be
between 0 and 120, is the number of bytes in label
. The
label
array is not padded or null-terminated.
