Paint It Red

So, I discover that I need to update the model-building macro I'm using, to get more accurate results. I'm reluctant to do this, partly because I hate tinkering with anything that's already working, and partly because the existing one was exactly 666 lines long and that amused me.

But since I had to do it, I decided to implement a bunch of other changes I've been meaning to make. So I go through this program that (as of this morning) worked, deleting bits here, adding bits there, changing variable names, all over the place. In particular, jumping through some very complicated hoops in the interests of making it Go Faster. (The sad thing about computer programs is you can't just paint them red like you can with cars.)

Then, very reluctantly, 'cos I know I'm about to subject myself to several painful hours of debugging and troubleshooting over a link that will probably die halfway through like it always does, I hit 'run'.

And, without a single error message, not one unmatched parenthesis or unrecognised variable name, it runs happily to the end of the program. And the program that used to take a solid half-hour to build a model now runs in about sixty seconds. And so far, I can't see anything obviously wrong with what it's produced.

This must be Thursday. I never could get the hang of Thursdays.
