It seems that people have mistaken my code example for the specific
instance were I needed a continue statement.

I only gave it so there was an example of a C use of the continue
statement. 
What I was asking; how would implement the code given, which realy is
just a general example, in Ada. Specifically so you could use it any any
loop were you needed to skip an iteration.

Thanks for the answers so far.
