To not have a property to pass the array back, try this:

DIMENSION laArray[1]
IF GetINIEntries(lcInitFile, lcSection, @laArray)
   ... got data from INI
ELSE
  ... failed to get data
ENDIF

Then in the function, return .T. for success and .F. for failure; add the following line too:

EXTERNAL ARRAY laArray

after the function header line. Now you are passing the array to the function via reference.
