in thread Optimising processing for large data files.

Yah, I thought so. My "fast" algoritm is, what, 1000x slower? So obviously I missed something important, and missed it pretty badly. <g>

I'd welcome any advice -- not that this matter for any pressing real project, but just to improve my skills.

Thanks, browserUK, look forward to your post....

[1nickt]: kgb not quite as simple as ... and ...; are interchangeable. There are edge cases, shown in perlsyn.
[1nickt]: Hm well actually I guess it's not the trailing semi-colon that's at issue there, it's disambiguation between the ellipsis and the binary flip-flop
[1nickt]: Although the example given does not produce an error as stated, on my perl.
[1nickt]: perl -wE 'say for map { ... } 1..3;' # "Unimplemented at -e line 1" ... <c>perlsyn says that should throw a syntax error...
[karlgoethebier]: 1nickt: "Edge cases..." Yes, it seems so. Thanks Nick
