files written by some systems set this value to -1. In general, it is
unsafe for systems reading system files to rely upon this value.
-@item int32 compressed;
+@item int32 compression;
Set to 0 if the data in the file is not compressed, 1 if the data is
compressed with simple bytecode compression, 2 if the data is ZLIB
compressed. This field has value 2 if and only if @code{rec_type} is
set to the length, in characters, of the variable label. The
documented maximum length varies from 120 to 255 based on SPSS
version, but some files have been seen with longer labels. PSPP
-accepts longer labels and truncates them to 255 bytes on input.
+accepts labels of any length.
@item char label[];
This field is present only if @code{has_var_label} is set to 1. It has
element denotes the additional discrete missing value.

The @code{print} and @code{write} members of sysfile_variable are output
formats coded into @code{int32} types. The least-significant byte
of the @code{int32} represents the number of decimal places, and the
