"When your edit, compile, edit, compile cycle starts to get above about 10 minutes, you start to pay an awful lot of attention to your source code…"
10 minutes? Luxury. Punched card jobs run in batches. 2 hours turn-round, max 3 runs a day with the compiler losing track after the first error and rejecting every subsequent line. Then you really paid attention to your source code.
Biting the hand that feeds IT
