I tried the source from this article, and got a complaint about syntax
(it should be 'upto' in the 'for', not 'to'), but after fixing that, it
compiled fine. Can you mail me the exact routine that is failing? I used
my V1.3 beta version of the compiler, but my log files going back to Jan 88
show no changes that could have fixed a bug like that. Also, since Draco
arrays are 0 origin (same as C's), the 'for' loop should be:

    for i from 0 upto dim(t, 1) - 1 do
	...
    od;

If all else fails, I can uuencode and mail you V1.3. (I haven't released it
yet since I want to do a whole new set of documentation.)
