By default, all the variables in a file are read. The DROP
subcommand can be used to specify a list of variables that are not to be
file on disk. Only the active dataset read from the file
is affected by these subcommands.
-@pspp{} tries to automatically detect the encoding of string data in the
-file. Sometimes, however, this does not work well encoding,
-especially for files written by old versions of SPSS or @pspp{}. Specify
-the @subcmd{ENCODING} subcommand with an @acronym{IANA} character set name as its string
-argument to override the default. The @subcmd{ENCODING} subcommand is a @pspp{}
-extension.
+@pspp{} automatically detects the encoding of string data in the file,

@cmd{GET} does not cause the data to be read, only the dictionary. The data
is read later, when a procedure is executed.

+The @subcmd{UNCOMPRESSED}, @subcmd{COMPRESSED}, and
+@subcmd{ZCOMPRESSED} subcommand determine the system file's
+compression level:
+
+@table @code
+@item UNCOMPRESSED
+Data is not compressed. Each numeric value uses 8 bytes of disk
+space. Each string value uses one byte per column width, rounded up
+to a multiple of 8 bytes.
+
+@item COMPRESSED
+Data is compressed with a simple algorithm. Each integer numeric
+value between @minus{}99 and 151, inclusive, or system missing value
+uses one byte of disk space. Each 8-byte segment of a string that
+consists only of spaces uses 1 byte. Any other numeric value or
+8-byte string segment uses 9 bytes of disk space.
+
+@item ZCOMPRESSED
+Data is compressed with the ``deflate'' compression algorithm
+specified in RFC@tie{}1951 (the same algorithm used by
+@command{gzip}). Files written with this compression level cannot be
+read by PSPP 0.8.1 or earlier or by SPSS 20 or earlier.
+@end table
+
+@subcmd{COMPRESSED} is the default compression level. The SET command
+(@pxref{SET}) can change this default.
The @subcmd{PERMISSIONS} subcommand specifies permissions for the new system
file. WRITEABLE, the default, creates the file with read and write
@vindex SYSFILE INFO
