Yes, it is.

No. Harbour doesn't generate RT error in such case. Maybe some RDDs
you are using make it but this are not core RDDs.
Probably you are using ADS RDD where we have:
if( !pArea->fPositioned )
{
/* TODO: it should return SUCCESS for Clipper compatibility */
return FAILURE;
}
And this is Clipper incompatible behavior local to ADS RDD only
and which probably should be fixed by simple modification to:
if( !pArea->fPositioned )
return SUCCESS;
what will restore original Clipper behavior.

So use the code I send to generate any error message you like.

For me from the beginning :-) but I'm afraid you missed original
Harbour behavior.
