The SAVE procedure causes the dictionary and data in the active
dataset to
be written to a system file.
OUTFILE is the only required subcommand. Specify the system file to be written as a string file name or a file handle (see File Handles).
By default, cases excluded with FILTER are written to the system file.
These can be excluded by specifying DELETE on the UNSELECTED
subcommand. Specifying RETAIN makes the default explicit.
The COMPRESS and UNCOMPRESS subcommand determine whether
the saved system file is compressed. By default, system files are compressed.
This default can be changed with the SET command (see SET).
The PERMISSIONS subcommand specifies permissions for the new system
file. WRITEABLE, the default, creates the file with read and write
permission. READONLY creates the file for read-only access.
By default, all the variables in the active dataset dictionary are written
to the system file. The DROP subcommand can be used to specify a list
of variables not to be written. In contrast, KEEP specifies variables
to be written, with all variables not specified not written.
Normally variables are saved to a system file under the same names they
have in the active dataset. Use the RENAME subcommand to change these names.
Specify, within parentheses, a list of variable names followed by an
equals sign (‘=’) and the names that they should be renamed to.
Multiple parenthesized groups of variable names can be included on a
single RENAME subcommand. Variables' names may be swapped using a
RENAME subcommand of the
form /RENAME=(A B=B A).
Alternate syntax for the RENAME subcommand allows the parentheses to be
eliminated. When this is done, only a single variable may be renamed at
once. For instance, /RENAME=A=B. This alternate syntax is
deprecated.
DROP, KEEP, and RENAME are performed in
left-to-right order. They
each may be present any number of times. SAVE never modifies
the active dataset. DROP, KEEP, and RENAME only
affect the system file written to disk.
The VERSION subcommand specifies the version of the file format. Valid
versions are 2 and 3. The default version is 3. In version 2 system
files, variable names longer than 8 bytes will be truncated. The two
versions are otherwise identical.
The NAMES and MAP subcommands are currently ignored.
SAVE causes the data to be read. It is a procedure.
