Hi Andrus and Sergey,

Some months ago, one of my clients reported data loss when they selected ASCII file output. The report was a single page of personal data that printed correctly, but created an ASCII file with some of the data missing.

I thought it may be an aberation with the data itself, but it now seems it may be a VFP REPORT FORM TO ASCII bug. Andrus, what version of VFP are you using? I use v7 with SP1.

Regards...Rex
