BTW, are there any string constants (e.g. 'Hello') which you have defined using characters in the ASCII range 0..31 or 127-255 (basically any character that requires you to use ALT-nnn)? I've found that these will cause spurious errors in systems running with DBCs. Usually replacing the expression with CHR() fixes the problem (though you may discover that the characters in the ASCII ranges described will often not display/print as expected).
