It possible?

var %i = $hget(0), %s = 0
while (%i) {
var %table = $hget(%i), %t = $hget(%table,0).item, %i = %i - 1
while (%t) var %s = %s + $len($hget(%table,%i).item), %s = %s + $len($hget(%table,%i).data), %t = %t - 1
}
return $bytes(%s).suf

but this is stupid, i think.

Just wanna know, how mIRC using memory, not himself, only bases: hash tables.
