Not necessarily. I'm testing with a table containing a dozen text
fields, each one large from 6 to 20 lines; so, when I run a select with
no 'limit n', (I suppose) the pager doesn't know how to split the text
field in order to accomodate it to the max no. of lines the screen can
show.
e.g., if rec. no 1 has a text of 15 lines and rec. 2 has 20 lines, the
pager should be able to split rec. no. 2 into two parts (9 lines to the
first - so that it can show together with rec. no. 1 (15+9=24) - and 11
to the second.

Thank you so much, Richard! I'll search the documentation for the
solutions you suggest which I'm not yet acquainted with ...
