Boolean variables
By default, the SPSS Statistics SAV DSC sets the value of the IBM SPSS Statistics variable to 1 to indicate that the response to the MDM variable was True, or 0 to indicate that the response was False.
To specify different values, use the
BooleanTrue and
BooleanFalse properties (see
Properties and settings used by the SPSS Statistics SAV DSC).

Variables that have codes lists
For an MDM variable of type Long, Double, Text, Boolean, or Date that has a codes list, the SPSS Statistics SAV DSC maps the codes list to additional IBM SPSS Statistics variables as follows:
▪If the value of the codes list's
EffectiveMaxValue property is 1, the SPSS Statistics SAV DSC writes the coded response to a single IBM SPSS Statistics numeric variable, as described in
Single-response categorical variables.
▪If the value of the codes list's
EffectiveMaxValue property is greater than 1, the SPSS Statistics SAV DSC writes the coded response to a multiple set of IBM SPSS Statistics numeric variables, as described in "
Multiple-response categorical variables.
