EXCEPTION

The EXCEPTION statement is similar to Firebird dynamic exceptions.

   EXCEPTION <exception_name> [<exception_text>]

<exception_name> is the name of an exception which may be tested using the ibec_err_Name function.

   execute ibeblock (divisor double precision)
   as
   begin
     i = 1;
     try
       if ((divisor is null) or (divisor = 0)) then
         exception INVALID_DIVISOR 'The divisor is invalid: NULL or 0';
       i = i/divisor;  
     except
       if (ibec_err_name() = 'INVALID_DIVISOR') then
         i = 0;
       else
         raise;
     end
   end
