Bad index expression error 610 with Six driver

[dlpastel]

Strangest thing has started happening. I use 5.2e with the Six driver rdd. I keep getting "Bad Index expression error 610 whenever I try to add code ANYWHERE in my program. I can even just put
FUNCTION TEST
RETURN
anywhere in my program and after I compile it and try to run the program I get the bad index expression error. It seems to happen the most on longer or date type sorts such as
Index on dtos(date)+tech to time1.nsx
If I take out the
function test8
return
then it works fine. It also works fine with ntx or cdx drivers.
I would switch to the cdx driver but I do not know how to convert my memo fields.

Any ideas?

Thanks,
Dan
