Re^2: Sliding window revisited: Is it OK to make it so?

Thanks LanX. I knew the links that you and choroba provided. But the advice given ibidem seemed to me like an endless loop. Probably yet another algorithm that I didn’t understand for a long time - or may be i got this notorious mental block again. But I begin to see the things more clearly now. And i guess that i need to read again some basic manpages to understand my stolen solution 🤪. Best regards, Karl

Sorry I have trouble understanding all of this, that's why I gave a generic hint The example code you showed seems to slide over a fixed array, but when dealing with huge files you need a dynamic approach. Otherwise you wouldn't get the file into memory. Unless there is "lazy" magic connected to the array via tie, but this must be in other parts of the module, which I never used In short, I'm confused what the question is and how to help.

Otherwise you wouldn't get the file into memory.

Unless there is "lazy" magic connected to the array via tie*, but this must be in other parts of the module, which I never used

In short, I'm confused what the question is and how to help.
