- Sub: Circular object ref compiles
-
- Hello:
-
- We are having difficulty making our stuff compile in multiple units. Our
- program consists of an assorment of incestuous (i.e. they all send messages to
- each other) classes. However, the classes are getting somewhat large and we
- would like to split them into separate compilation units.
-
- In order to do so, we have appempted to create a unit with the declaration for
- several classes, but without the code (implementation section) for the class
- methods.
-
- According to the MPW Pascal version 3.0 manual, page 286, a unit is not
- required to have an implementation section. Further, we read the description
- of the $J+ option (same manual) to indicate that with J+, the interface may be
- provided without the implementation (with the method code resolved in a
- separate unit). Unfortunately, we have not been able to get past the
- unimplemented method errors when compiling our declaration unit.
-
- I'd appreciate any suggestions on how to compile this unit, or other ways to
- get around the circular uses problem.
-
- Than you very much,
- Eric
