Unfortunately, you can't set the MAX_LENGTH property, so you'll need to do something like this:

Given a Block named "block1" containing two items "size" and "chrfld", create a procedure called "PR_CHECK_SIZE":

   PROCEDURE pr_check_size is
   begin

     if length(:block1.chrfld)>nvl(:block1.size,0) then
         message('Error: Max size is '||
                 to_char(nvl(:block1.size,0)));bell;pause;
         raise form_trigger_failure;
     end if;

   END; Now create a WHEN-ITEM-VALIDATED trigger on both the SIZE field and the CHRFLD field containing a call to PR_CHECK_SIZE. Crude, but it works.

Anyone else got a better way?
