is affected by these subcommands.

-@subcmd{IMPORTCASE} can be used to limit the number of cases read from the
-input file. With the default setting, ALL, all cases in the file are
-read. Specify FIRST @var{max_cases} to read at most @var{max_cases} cases
-from the file. Use @subcmd{PERCENT @var{percent}} to read only @var{percent}
-percent, approximately, of the cases contained in the file. (The
-percentage is approximate, because there is no way to accurately count
-the number of cases in the file without reading the entire file. The
-number of cases in some kinds of unusual files cannot be estimated;

character is a @pspp{} extension.
-By default, a character specified on @subcmd{QUALIFIER} cannot itself be
-embedded within a field that it quotes, because the quote character
-always terminates the quoted field. With ESCAPE, however, a doubled
-quote character within a quoted field inserts a single instance of the
-quote into the field. For example, if @samp{'} is specified on
-@subcmd{QUALIFIER}, then without ESCAPE @code{'a''b'} specifies a pair of
-fields that contain @samp{a} and @samp{b}, but with ESCAPE it
-specifies a single field that contains @samp{a'b}. ESCAPE is a @pspp{}
-extension.
+The character specified on @subcmd{QUALIFIER} can be embedded within a

The @subcmd{DELCASE} subcommand controls how data may be broken across lines in
