thank you. I can watch for long lines and then put up an alert telling 
them that it's there, they just cannot see it.

Also, these limits should be in the docs. The old Hypercard manual had 
a back section on limits and I reached some of them. I'd like to see 
limits stated in the run rev docs.

uh, no, I actually wanted to display the results of an SQL query and it 
had no spaces and was longer than that limit. Normally the results are 
viewable and the really long results get copied into a text document 
and formatted for viewing. But in this case, it looked like the results 
were blank and that was my assumption (something went wrong with my 
code?) until on a whim I copied and pasted into a text document and saw 
that it was all there.

But, thank you very very much for an understanding of the limits. Now I 
can add an alert when the data is invisible.
