Hello.
Maybe I wrong but I use to call:

- SCRIPT ---> I mean client mIRC
- ADDONS ---> Is a code so is always a script. A script (mIRC) , may have inside many addons.

In my case I have some addons to check badwords, nick change flood, join flood, and so on.
Some of them have the same string about setting var %:

[c]var %i 1 | while (%i <= $lines($bwfile)) { ... }[/c] like here Sample 1

[c]var %i 1 | while (%i <= $comchan($newnick,0)) { ... }[/c] like here Sample 2

[c]var %i = 1, %badwords = 1 ...[/c] like here Sample 3

May it cause conflicts because all these addons are parts of the same script?

Thanks
