You can create a report which wouldn't use any tables, but you still need at least one dummy cursor with one record to be able to run it, because the Report Form command has a range clause, i.e. it is assumed to be done over a workarea which has something open.

As for printing longer strings, the 255 char limit is inherent to VFP's print engine; I have had trouble with expressions which returned more than that, or longer memos. Your solution is OK for one line; here's how I'd go to print it into a column:

set memo to < your max width of column goes here >
for i=1 to memlines(thisform.message)
@prow()+1, 5 say mline(thisform.message, i)
endfor

Sorry, can't try your code with a printer, I write these messages at home, no printer at hand.
