• The only specification is the keyword COMPRESSED or UNCOMPRESSED. There are no<br />

additional specifications.<br />

• Compressed data files occupy less disk space than do uncompressed data files.<br />

• Compressed data files take longer to read than do uncompressed data files.<br />

• The GET command, which reads SPSS-format data files, does not need to specify whether<br />

the files it reads are compressed or uncompressed.<br />

Only one COMPRESSED or UNCOMPRESSED subcommand can be specified per XSAVE<br />

command. COMPRESSED is usually the default, though UNCOMPRESSED may be the<br />

default on some systems.<br />

PERMISSIONS Subcommand<br />

The PERMISSIONS subcommand sets the operating system read/write permissions for the<br />

file.<br />

READONLY File permissions are set to read-only for all users. The file cannot be saved<br />

using the same file name with subsequent changes unless the read/write permissions<br />

are changed in the operating system or the subsequent XSAVE command<br />

specifies PERMISSIONS=WRITEABLE.<br />

WRITEABLE File permissions are set to allow writing for the file owner. If file permissions<br />

were set to read-only for other users, the file remains read-only for<br />

them.<br />

Your ability to change the read/write permissions may be restricted by the operating system.

Hooray! Your file is uploaded and ready to be published.
