Of course routine_id is case sensitive. I always wrap routine_id, eg:

function routineid(sequence name)
integer r
	r=3Droutine_id(name)
	if r=3D-1 then ?9/0 end if
	return r
end function

so it fails a bit more obviously. However, you do need to make sure
this is right at the end of the code, after all the routines it will
reference and before the bank of setHandler etc calls, or, sometimes
more bizarrely, call it via r_routineid=3Droutine_id("routineid") 

I hope that makes sense. Although it can be quite confusing at first,
it has made my code much more maintainable.

PS No, I still can't think of a case where you'd pass routine_id an
unrecognised string and want it to return -1 quietly instead of
stopping with an error. Rob claims it would break existing code.
