The length of the item depends on the version of mIRC you use. It was increased a lot in 6.35. Not sure what it is, but it's probably in
versions.txt ... maybe 4096 characters or something?
One thing to consider... are hash tables your best option for what you're doing? Is the data used all the time or just occasionally? If it's not used that often, a text file or some other method might be better.
