I wonder if it's Error 13 (Alias not found)?

Also in earlier versions we used to hack the CDX files with low level file functions to remove this kind of bad indexing. In that case we had a UDF that created a thermobar, but it was the same idea.

>Well, if he knows what the indexes are, yeah, he can hard code them, and recreate them by deleteing the orginal CDX opening the table and INDEX. But if he planned to convert them all (IOW he didn't know what the expressions were), he'd have to open the table to get at them, which causes the error that he wants to supress.
