-You can use @cmd{MODIFY VARS} to reorder, rename, or delete variables.
-
-@display
-MODIFY VARS
- /REORDER=@{FORWARD,BACKWARD@} @{POSITIONAL,ALPHA@} (@var{var_list})@dots{}
- /RENAME=(@var{old_names}=@var{new_names})@dots{}
- /@{DROP,KEEP@}=@var{var_list}
- /MAP
-@end display
-
-At least one subcommand must be specified, and no subcommand may be
-specified more than once. @subcmd{DROP} and @subcmd{KEEP} may not both
-be specified.
-
-The @subcmd{REORDER} subcommand changes the order of variables in the active
-dataset. Specify one or more lists of variable names in parentheses. By
-default, each list of variables is rearranged into the specified order.
-To put the variables into the reverse of the specified order, put
-keyword @subcmd{BACKWARD} before the parentheses. To put them into alphabetical
-order in the dictionary, specify keyword @subcmd{ALPHA} before the parentheses.
-@subcmd{BACKWARD} and @subcmd{ALPHA} may also be combined.
-
-To rename variables in the active dataset, specify @subcmd{RENAME}, an equals sign
-(@samp{=}), and lists of the old variable names and new variable names
-separated by another equals sign within parentheses. There must be the
-same number of old and new variable names. Each old variable is renamed to
-the corresponding new variable name. Multiple parenthesized groups of
-variables may be specified.
-
-The @subcmd{DROP} subcommand deletes a specified list of variables
-from the active dataset. @cmd{MODIFY VARS} may not be used to delete
-all variables from the dictionary; use @cmd{NEW FILE} to do that
-(@pxref{NEW FILE}).
-
-The @subcmd{KEEP} subcommand keeps the specified list of variables in the active
-dataset. Any unlisted variables are deleted from the active dataset.
-
-@subcmd{MAP} is currently ignored.
-
-If either @subcmd{DROP} or @subcmd{KEEP} is specified, the data is read;
-otherwise it is not.
-
-@cmd{MODIFY VARS} may not be specified following @cmd{TEMPORARY}
-(@pxref{TEMPORARY}).
