Overview (USE command)

USE designates a range of observations to be used with time series procedures. Cases outside the defined range are filtered but not deleted from the active dataset unless the /PERMANENT subcommand is specified.

Basic Specification

The basic specification is either the start of the range, the end of the range, or both. You can also simply specify the keyword THRU or ALL.

  • The default start is the first observation in the file, and the default end is the last observation.
  • The keyword THRU is required if the end of the range is specified.
  • The keyword ALL defines a USE range starting with the first observation and ending with the last observation in the series. It can be specified to restore processing to the entire series.
  • The keyword THRU by itself is the same as specifying the keyword ALL.

Operations

  • USE is ignored by the utility procedures CREATE and RMV. These procedures process all of the available data.
  • The DATE command turns off all existing USE and PREDICT specifications.
  • FILTER and USE are mutually exclusive. USE automatically turns off any previous FILTER command, and FILTER automatically turns off any previous USE command.
  • The SORT command automatically turns off any previous USE command specification.
  • USE remains in effect in a session until it is changed by another USE command or until a new DATE, FILTER, or SORT command is issued.

Limitations

  • A maximum of one range (one start and/or one end) can be specified.
