Thanks Sergey,

I've tried it, one small problem - loading the data from the blobfile using

the routine below, when I load RVF data that contains 'tags' (e.g. I have

used tags to store http:// address info), it generates a 'EConverError' on

the tag data, saying it is not a valid integer value.

Any ideas?
