The "Global File Structure" section points out that data specifications for subfields of a Multiple are kept in a subsidiary data dictionary. Such a sub-dictionary is stored in the global ^DD(sub-dictionary_number); where sub-dictionary_number is a number with a fractional portion. For example, the specifications for the RESPONSES Multiple in the (fictitious) ORDER (#100) file, are stored in ^DD(100.045). Normally, when a new Multiple-valued field is created, VA FileMan automatically assigns the fractional sub-dictionary number. The developer, however, is allowed to choose the desired number.
When creating a new Multiple field, (Modify File Attributes [DIMODIFY] option), if you are a developer, you are asked in a "popup" window for the global subscript at which to store the data element being defined. Under this question is the SUB-DICTIONARY question. The RESPONSES Multiple in the (fictitious) ORDER (#100) file would have been defined like Figure 390.
