SPSS® 12.0 Command Syntax Reference

1432 REREAD
Subcommand Order
Subcommands can be specified in any order.
Syntax Rules
• REREAD is available only within an INPUT PROGRAM structure.
• Multiple REREAD commands can be used within the input program. Each must be followed
by an associated DATA LIST command.
Operations
Example
• REREAD causes the next DATA LIST command to reread the most recently processed
record in the specified file.
• When it receives control for a case, REREAD places the pointer back to column 1 for
the current case and begins reading data as defined by the DATA LIST that follows. If the
COLUMN subcommand is specified, the pointer begins reading in the specified column
and uses it as column 1 for data definition.
• REREAD can be used to read part of a record in FIXED format and the remainder in LIST
format. Mixing FIXED and FREE formats yields unpredictable results.
• Multiple REREAD commands specified without an intervening DATA LIST do not have a
cumulative effect. All but the last are ignored.
