overriding methods

[Hilton Grimbeek]

I am new to PowerBasic and at the moment struggling with terminology and a new way of doing things. However, I must say I have been enjoying the ride.
My present puzzle is a compiler error I get - MISMATCH WITH PRIOR DEFINITION - when to me it looks exactly the same. I have a parent class that contains methods I want overridden as well as a class that inherits from it. This contains the OVERRIDE methods. The parent methods to be overridden look like:

'=============================methods to be overriden=============
METHOD setBeginOfFile()
mFile.clear()
END METHOD

METHOD setEndOfFile()
mFile.clear()
END METHOD

METHOD checkRange() AS INTEGER
METHOD = 0
END METHOD

METHOD checkFilter() AS INTEGER
METHOD = 0
END METHOD

METHOD setColumnSearch(key AS STRING)
END METHOD

METHOD columnClicked(col AS INTEGER)
END METHOD

METHOD putInGrid(row AS INTEGER, refresh AS INTEGER)
END METHOD

METHOD setUpColumns
END METHOD

METHOD getAssociatedData AS INTEGER
METHOD = 0
END METHOD
'=============================end of overrides====================

The derived class looks like this:

CLASS myLv
CLASS METHOD CREATE()
mybase.create()
END METHOD
INTERFACE myLvif
INHERIT cgListview,cgLview
OVERRIDE METHOD checkFilter() AS INTEGER
IF mybase.mFile.getfield("fgactive") <> "1" THEN
METHOD = -1
ELSE
METHOD = %OK
END IF
END METHOD
END INTERFACE
END CLASS

The line that gives trouble is the OVERRIDE METHOD.

Can anyone please put me straight. Thanks


DON'T WORRY, I DISCOVERED THAT IF I USE "AS LONG" INSTEAD OF "AS INTEGER" THE COMPILER IS HAPPY. I MUST HAVE MISSED SOMETHING IN THE DOCUMENTATION
