Because it allows me to 'hardcode' the numbers in the substrs.
F4_N() and F4_L() are constant subs which get optimised away during compilation, leaving hardcoded numbers which are faster than variables.
The memory saving comes from packing the fields into single strings; the performance comes from asking the sub to do as little as possible.
That said, by explaining that, I've spotted another couple of optimisations; and a potential bug. I'll get back to you with a revised version 2 days from now.
