C.9 Value Label Records

Value label records have tag code D. They have the following format:

• Variable count (integer).
• List of variables (strings). The variable count specifies the number in the list. Variables are specified by their names. All variables must be of the same type (numeric or string).
• Label count (integer).
• List of (value, label) tuples. The label count specifies the number of tuples. Each tuple consists of a value, which is numeric or string as appropriate to the variables, followed by a label (string).
