Hi Marcell.

I came across the same problem when I was writing "A Beginner's Guide To
Euphoria", the tutorial program. I wanted to create something that allowed
me to index a file randomly. I ended up writing a separate index file
that served as a go-between to the program and the target file. Each index
record contained the byte position to seek() to randomly address each
part of the target file. It's similiar to an access path on an AS/400
physical keyed file.

I'm not familiar with B-Trees, B+Trees or ISAM files, but if you want help
writing procedures to maintain a relational database similiar to
the AS/400 system, please contact me at moggie at interlog.com

Thank you
