Contains a comma-separated list of possible values for a character-type dataslot when there is a limitation in the values that can be chosen. For example, if the only allowable values for a Color dataslot are red, green, and blue, the values of the Choices property for the DataSlot would be "Red,Green,Blue".
The Choices property applies only to String and Character types. The property will have the Unknown value (?) for all other data types (and the property value may also be the Unknown value (?) for a CHARACTER and LONGCHAR, if choices were never defined for the dataslot).
