In many MultiValue implementations, a phrase only uses attributes 1 and 2. All others are treated as comments. So the VOC entry
0001 PH 0002 F1 F2 0003 FN
will list only F1 and F2 on most implementations.
The exceptions, among the supported emulations, are Reality and jBASE. Since Caché strives to provide a superset of MultiValue functionality, it performs like this latter set. That is, a phrase may use any or all of its attributes.
An attribute of a phrase whose first character is an asterisk is treated as a comment, that is, it is ignored.
