FILE Subcommand (UPDATE command)
FILE
identifies each input file. At least two FILE
subcommands are
required on UPDATE
: one specifies the primary file and the other a transaction
file. A separate FILE
subcommand must be used to specify each transaction file.
- The first
FILE
subcommand must specify the primary file. - An asterisk on
FILE
refers to the active dataset. - The files must be IBM® SPSS® Statistics data files or datasets available in the current session. File specifications should be enclosed in quotes.
- All files must be sorted in ascending order according to the variables
specified on
BY
. - The primary file cannot contain duplicate values for the key variables. However, transaction files can and often do contain cases with duplicate keys (see Operations).
PASSWORD Keyword
The PASSWORD
keyword
specifies the password required to open an encrypted IBM SPSS Statistics data
file. The specified value must be enclosed in quotation marks and
can be provided as encrypted or as plain text. Encrypted passwords
are created when pasting command syntax from the Save Data As dialog.
The PASSWORD
keyword is ignored if the file is not
encrypted.
