Thanks, I think that fixes it although I'm still working through the 
affected unit.

I presume I'm correct in assuming {$mode delphi} operates strictly on 
the syntax of the current unit without affecting cross-unit operations.

Are there cases where it can't be used? Specifically, can it be put in a 
Lazarus .lpr file where this is a transcript of a Delphi .dpr?
