Specifying the Plan File and the Data File

The CONJOINT command provides a number of options for specifying the plan file and the data file.

• You can explicitly specify the filenames for the two files. For example:

  CONJOINT PLAN='CPLAN.SAV' /DATA='RUGRANKS.SAV'

• If only a plan file or data file is specified, the CONJOINT command reads the specified file and uses the active dataset as the other. For example, if you specify a data file but omit a plan file (you cannot omit both), the active dataset is used as the plan, as shown in the following example:

  CONJOINT DATA='RUGRANKS.SAV'

• You can use the asterisk (*) in place of a filename to indicate the active dataset, as shown in the following example:

  CONJOINT PLAN='CPLAN.SAV' /DATA=*

  The active dataset is used as the preference data. Note that you cannot use the asterisk (*) for both the plan file and the data file.
