Find recs and put them into a memo as string (1 Viewer)

[aprentice]

I want to build a function which finds some recs
with SELECT WHERE statement
and then convert some (specified by me) fileds of these recs into string and concatenating them to a signle string and putting to a memo field of a report.
Sounds complicated but it isn't.

My only problem is to the converting some fields to string.

Any ideas?
Thnx in advance
