Hey

I'm from Brazil and I not speak english very well, I wait that you they understand me...

On mIRC 6.17 the $regsubex return this
$regsubex(Test,/(.)/g,\0) return 4444 (number of matches)

On mIRC 6.2 the $regsubex return this
$regsubex(Test,/(.)/g,\0) return 4321 (number of remain matches)

The \0 on help says it: "0 = number of matches"

Then the correct one is in the mIRC 6.17, but \0 of the mIRC 6.2 is well util and could be replace by one \r and the \0 fixed...

Thank You...
