Inheritance Use Question

[Lee Furr]

Using Direct Interface Block definitions with Classes, and am running into an error when utilizing a "UserWritten" Inherit statement in a Direct Interface Block.

The Error, a "CLASS Expected" error associated with the use of an Inherit Statement in a Direct Interface Block, does not occur when the Direct Interface Block is excluded. (Though the same "UserWritten" Inherit Statement is still included in the derived Class implementation code.)

Example Code:

   INTERFACE CLASS1Interface
      INHERIT IUNKNOWN

      Method aRoutine() as Long

   END INTERFACE

CLASS CLASS1
   INTERFACE CLASS1Interface
      INHERIT IUNKNOWN

      Method aRoutine() as Long
      End Method

   END INTERFACE
END CLASS

'Code compiles as shown with the Direct
'Interface Block below commented out.  However, 
'if conditional Direct Interface Block 
'below is [u]included[/u] in the compile,
'changing #if(0) to #if(1), then the
'compiler complains...
' "CLASS Expected"
' Compiler complains about the 
' inheritance ONLY with the 
' Direct Interface Block below active.
'--
[color=blue]
#if(0)  
   INTERFACE CLASS2Interface
      [b]INHERIT CLASS1, CLASS1Interface[/b]  '<-Not Happy

      Method aTest() as Long

   END INTERFACE
#endif
[/color]

CLASS CLASS2
   INTERFACE CLASS2Interface
      [b]INHERIT CLASS1, CLASS1Interface[/b]   '<- Happy
      
      Method aTest() as Long
      End Method

   END INTERFACE
END CLASS


function pbmain()
   waitkey$
end Function

It other words, it (the compiler) is happy with "INHERIT CLASS1, CLASS1Interface" as implementation code but not as definition code that is part of a Direct Interface Block. Any insights as to why the Inherit Statement "INHERIT CLASS1, CLASS1Interface" compiles happily until a Direct Interface Block definition is included?
