You can create your own printed manual using the RTFer stack: <http://www.poetickat.com/revdocs/index.html>

You can perform math functions just by describing them. For the above, for example, you might use:

put 5 + field "some field" into fld "another field"

To verify that something is a number, just say so:

if field "some field" is a number then
  put 5 + field "some field" into fld "another field"
else
  answer "Please enter a number!"
end if
