in thread Generate the perl sequence 1, 11, 111, ....

One interesting and useful sequence that springs to mind is:
2, 3, 5, 7, 11, 13, ... # Prime numbers.

[choroba]: but undef %hash and %hash = () both work, too, but the first one keeps the memory allocated, while the latter makes it available for other parts of the program.
[choroba]: iirc
[perldigious]: karlgoethebier: Well it is a pretty old and complicated (for me) bit of code I wrote (poorly by my current standards), so I'm expecting everything to break when I add the scoping and find out what else is undesireably scope changed. :-)
[perldigious]: Ah, thanks choroba, that sort of thing was precisely what I was wondering when I asked.
[perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
