Are there any basic rules of thumb that an "Intermediate" level
programmer(as I was declared by my CS teacher) should follow in Ada as
regards data types and spec files?
I've made a BIG point of avoiding unecessary coupling as you pointed out.
As I'm not writing very "large" programs in Ada yet, I havent really run
into any problems with Data types and elaboration. Is there anything that
I should be practicing regularly, which might be peculiar to Ada95, that
would help me avoid problems once I get into developing "larger" pieces
of software?
