Resolution:
Correct the code; then recompile.
Example:
In the following example, the RETURNING RET STRING syntax is illegal and should be RETURNING RET TO STRING-ARRAY[0].
class-id a.
method-id main static.
declare d as type System.Func[string]
set d to
delegate(params string-array as string occurs any returning ret as string
*>set ret to string-array[0]
end-delegate
end method.
end class.
