You cannot do this in I4GL without using some sort of preprocessor. And it would be non-trivial to implement, especially considering that you cannot pass arguments into a function called by WHENEVER ERROR, and when you remember that the error handling function need not be in the same module as the code which invokes it. As was pointed out by someone else, the module name and line number are recorded in the error log file if you have one active, though that is of limited (zero?) value in the context you give.
