11.19 VARIABLE ROLE

     VARIABLE ROLE
             /role var_list
             [/role var_list]...

VARIABLE ROLE sets the intended role of a variable for use in dialog boxes in graphical user interfaces. Each role specifies one of the following roles for the variables that follow it:

INPUT
An input variable, such as an independent variable.
TARGET
An output variable, such as an dependent variable.
BOTH
A variable used for input and output.
NONE
No role assigned. (This is a variable's default role.)
PARTITION
Used to break the data into groups for testing.
SPLIT
No meaning except for certain third party software. (This role's meaning is unrelated to SPLIT FILE.)

The PSPPIRE GUI does not yet use variable roles as intended.
