1556 SURVIVAL
WRITE Subcommand
Format
WRITE writes data in the survival tables to a file. This file can be used for further analyses or
to produce graphics displays.
• When WRITE is omitted, the default is NONE. No output file is created.
• When WRITE is used, a PROCEDURE OUTPUT command must precede the SURVIVAL
command. The OUTFILE subcommand on PROCEDURE OUTPUT specifies the output file.
• When WRITE is specified without a keyword, the default is TABLES.
NONE Do not write procedure output to a file. This is the default when WRITE is omitted.
TABLES Write survival-table data records. All survival-table statistics are written to a file.
BOTH Write out survival-table data and label records. Variable names, variable labels,
and value labels are written out along with the survival table statistics.
WRITE writes five types of records. The keyword TABLES writes record types 30, 31, and 40.
The keyword BOTH writes record types 10, 20, 30, 31, and 40. The format of each record
type is described in Table 1 through Table 5.
