In Control

Are you aware that SPLat, like any decent programming language, lets you use meaningful names for inputs, outputs, RAM variables etc? Which of the following fragments say the most to you:

      WaitOn    5

      Off       3

or

      WaitOn    FullSensor

      Off       FillValve

Imagine now that you refer to the FullSensor 75 different times in your program. Then accidentally Production wire the sensor to input 4 rather than input 5 on 250 control boxes.
Which job will be easiest and safest:

1. Rewiring 250 boxes

2. Changing

      WaitOn    5

to

      WaitOn    4

in 75 places in a 3000 line program.

3. Changing

      FullSensor   iEQU    5

to

      FullSensor   iEQU    4

in one place?

And which form will it be easiest for you or someone else to read in 6 months or 6 years time?
One of the golden rules of programming, and a sign of a professional, is to write a program in a style that is clear and uncluttered. Use named "resources", use whitespace to effectively separate functional sub-blocks of code and use comments to describe what a block of code is doing.
