1. ��continue�� reserve word support?
Ada has no ��continue�� word.


   outer:loop
         execute_some_Statement_here0;
      EXIT when some_condition;
         execute_some_Statement_here1;
      inner: loop
         execute_some_Statement_here3;
         IF some_condition_is_true THEN
            goto outerContinueLabel;
         END IF;
         execute_some_Statement_here4;
      end loop inner;
         execute_some_Statement_here5;
      <<outerContinueLabel>>
         null;
   end loop outer;

It's hard to read,
How should I do to remove "goto"  ....?



2. type declare problem

I know there are some choices can apply to my program.
( a ). Type stock_price is new float;
( b ). Type stock_price is digits 5;
( c ). Subtype stock_price is float;

I know if I use ( c ) style.  I can mix stock_price and float type to
compute together.

if we don't consider ( c ) style, only  consider (a) and (b).
which style is best?


3. possible assign a IEEE754 NaN value to float type variable?

I use gwindows.database package to access atabase. It is great and very easy
to use.
Unfortunately, my database exits some null value in a table.
Many other languages will assign a NaN value to variable if it is null value
and float type.
Can I assign a NaN to float variable, like other languages?
