After prowling around my hard drive I found that the v5.5.4 docs are the
most recent I can find which have Release Notes describing the new field
features.
Among the other critically important information there currently absent
from the docs is this bit that answers my question:
Explicit line-breaks in fields (5.5 DP2 – experimental)
The engine will now interpret a numToChar(11) character in a
field paragraph as an explicit line- break when the (effective)
dontWrap of the paragraph is false. This allows multiple ‘lines’
to be displayed within a single paragraph.
The formattedText property has been updated to map any explicit
line breaks to newlines.
Note that since the vGrid property turns dontWrap on for the
paragraph, using the line-break char in table paragraphs will have
no effect.
The Message Box doesn't have its dontwrap set, so there's no way to see
the natural wrappings of your text there. As a workaround during
development I've found you can simply add a field with dontWrap set to
true and put any data you need to review there instead.
