Is this a bug or am i missing something?

It has always worked this way. If you are unsure you can always add;

#UNIQUE VAR ON

to your source file.

The problem is that if you change it to "REDIM ArrayName(number) AS type", it does create a new array with scope LOCAL.
This is undocumented (Help just says that "as type" is optional).

ISTR this "phenomenon" being reported by others in the context of "procedures, " not just in the context of "Interfaces" ... anything other than simple 'REDIM arrayname(new_bounds) [ end of statement]' will create a 'new' array using the type and scope specified.

I just, out of force of habit now that everything works, always do this:

 Procedure Foo (params) 

  LOCAL   arrayname() AS type      ' define the symbol 

 ..... 
  REDIM arrayname (number)        '  create the array so it exists and may be used 
                                  ' datatype and scope already defined above

Apparently I won't have to change anything should I desire to create my own INTERFACEs with METHODs.
