But we would never want to do that in a program, and indeed
Ada here helps us avoid the nasty habit of embedding odd
escape sequences in strings in C without any comments, often
with a result of making the program non-portable. The proper
coding in Ada would be:
Clear_Screen : constant String := ASCII.ESC & "[2J";
-- ANSI escape sequence for clearing screen. Modify to
-- meet requirements of your system.
Put (Clear_Screen);
It is almost always wrong to have mysterious constants in code!
