Try to write short routines with locally-scoped variables that are named to clearly illustrate their meaning, not their data type. The very worst thing that can ever happen is that I am trying to understand the meaning of your code ... you got mashed by a bread truck so I can't ask you ... and I get it wrong. I overlook something. I misinterpret it. Or even, your variable-names suggest something that is not or is no longer true. "K. I. S. S." I can only read your code – I cannot read your mind. But you can clearly suggest to me what you were thinking at the time.
