Hello,
In the February edition of iSeries News there is an excellent article about runtime arrays by Julian Monypenny.
True. There have been LOTS of articles on this subject over the past 10 years. Lots and lots and lots of them. I still struggle with one thing: Why would anyone want to do this?
Why create this level of complexity in your code to save a few hundred kilobytes? Surely your iSeries, like mine, uses a very efficient memory handling system that will keep the stuff you're not using on disk where a few hundred kilobytes, or even megabytes, don't really matter. Surely, even if it wasnt' efficient, the amount of memory your array used would be completely insignificant on any computer created this century.
Now, if you're doing it purely with pointer logic in order to exceed the 32767 limit on array indexes, then I can see why you'd do it. But, to avoid 50 or so elements of a small array being allocated? You've got to be kidding me.
