Stagnant -- doesn't change.
Empty -- they're blank cards.

Both words are pretty common in English.

Even a competent RDB-er as yourself is familiar with programming languages making decisions. I'm sure your experience with SQL must have included close brushes with the WHERE clause. That's how users are able to discriminate between getting ALL tuples or just the tuples they want. "WHERE" clauses are SQL expressions that reflect decisions.

They're not unlike IF-THEN statements in other languages. This is how programs decide what to do next based on a condition. For instance:

    IF student not familiar with basic programming concepts THEN explain     control flow using small words.

No, the meaning of what's on the card is in the reader's head. Perhaps maybe even yours. Without an understanding of English the meaning of what people write in English is, well, meaningless. Whether the consumer is human or machine the meaning of what's written on the card depends on the consumer. The 3x5 hasn't a clue what the meaning is, although a 3x5 has a purpose (given it by intelligent design)--to preserve information inscribed on them. A 3x5 doesn't know the meaning of what's written on it--only that something is written on it and it shouldn't erase or alter it.

Well, your behavior chose to both USE your computer and DECIDE to be abusive and argumentative. A program could be written to mimic that behavior but it would have little appeal and even less utility.

Was there a constructive comment in there that furthered mutual understanding or promoted your argument? Your prejudice and lack of reading comprehension is betrayed by your prediction of what I might write next. Though you did say something we agree on--that it would be nonsense to assert RM is inspired by OM.

Your unwillingness to consider what others write doesn't make them idiots--it sentences you to remain willfully ignorant and irrelevant.
