Cross Referencing undefined symbols
Only SNiFF+ symbols (symbols residing in the Symbol Table and shown in the Symbol Browser) can be cross referenced. These symbols must be defined in files in the Project Tree. If a symbol is outside of the files of a given project and its subprojects, it is inaccessible to SNiFF+, and will be displayed as undefined. Undefined references are always shown in the Cross Referencer. An example is CALENDAR, which is, though WITH-ed and may be available to the compiler, not included in the project.
