Follow Cross References

In this chapter, you will learn how to use the Cross Referencer to follow references in your source code.
With the Cross Referencer, you can answer questions like "What subprograms are called from this function" or "Where this package is referred to by" or "Where this object's value is reassigned?". The received cross-reference information can be filtered and refined in many ways.

| Note
| To avoid overwhelming the user with unimportant reference information, local references are not displayed in SNiFF+. That is, if a symbol is referenced in the same scope it was defined, it will not be shown in the Cross Referencer. As package subprograms and objects are considered as bearing the highest importance, references to them are always displayed (even if local). References displayed in SNiFF+ can appear only in subprogram bodies. References in any other places are discarded.
