There's an annoying bug in the /Hsave command.
It's having problems with saving the [ ] characters. I know it's an .ini problam, but there is a solution for that. just replace those character with some other characters that aren't in use, like 244 and 245 and then make the /Hload command translate them back to the [ ] characters.

I dont know anything about hash tables, but maybe try using $chr(91) and $chr(93)? they are [ and ], respectively.

Hope it helps,
Zyzzy

EDIT -> BTW, $chr(244) and $chr(245) are extensively used in Portuguese

And what if those 2 character are used? Someone will come here and complain just like you did :P
