I was going to suggest polyGrid. I used it when it was still in development
to solve the text overrun problem. It works like the datagrid, only loading
the visible text in batches as you scroll and performs very well.

My testing attempts, like Bernd’s, show that the important “limits” are not
just what LC can display in a field but what it can display without making
things too slow. I am also wondering if the new polyGrid has different
characteristics, either its absolute limits or its performance when

As I mentioned, I wanted to make sure the field had scroll capabilities. ;-)

Jacque noted the machine limits, but I'm curious about a human question:
At
The theoretical field text limit is about 4 GB but the practical limit
depends on available RAM.

This seems to mean we can have a 65k long line only if each character’s width
is around half a pixel.
And that if the character width is 10 pixels the

The stack I made to test this became corrupted after a couple of runs. I guess
the way to do this is to increase the length until a crash, not decrease.

But I assume that there is a value where a field can be loaded and display a
large amount of text. It would be simple to find that value if LC didn’t crash
each time it was attempted along the way.

You want to display 1.39 GB in a field? Will it scroll?
I made a quick test stack that created a variable with a length of 1.4 GB. No
problem.
But when I tried to put that variable into a field, LC crashed. When I tried to
put 140 MB into a field, same crash. I did not continue to
I thought the theoretical limit was 4GB (32bits of characters) but I may
be wrong or there may be practical limits below that threshold.
