Memo field contents may be very long and may contain chr(13) and chr(10) indicating line end. So the solution depends on how you need to handle these line breaks and long content in the particular record and on how they need to be inserted into text file. Otherwise something like this:

use (yourtable)
lnfp=fcreate("outfile.txt")
scan
fputs(lnfp,alltr(memofield))
endscan
=fclose(lnfp)

>I got a table which got one memo field only.
>I will generate 30-50 records each time and then export them into *.txt format.
>My txt file format must be 1ine feed.
>It means. 1 record pre 1 line .
>How can i do that ???
>
>Thanks in advance.
