If sz& is corrupted, it implies the saved handle ( h& retrieve from the global array gFBIndxAry& ) and/or its contents are corrupted. How it got that way would require extensive debugging sessions with your code.

The sz& is definitely getting corrupted and not returning the correct value.    But it happens only in a particular database I have from a customer.
I have not figured out why this is occurring.

I have already began using CFIndex in my newer code but retrofitting it isn't worth the effort, unless I cannot come up with a way around this.

thanks for your suggestions.
