TTYs are crutches for weak minds. Real men design their program,
then they keypunch the corresponding code and drop the cards off. Later
in the day, they pick up their printout from their correctly written
program.
If a change in the code is required, just punch up new cards for the section
to
be modified. Line mode editors are an abomination.
And don't even get me started on glass TTYs and "full-screen" editors.
What an incredible extravagant waste of processor CPU and I/O,
not to mention the programmer's time waiting for the screen to repaint.
