The mIRC Scripting Language, abbreviated as mSL, is an event-driven, procedural scripting language embedded inside the mIRC client.

Although widely used to make bots to automatically manage a channel, it can also be used to create: basic games, small functions and macros, play music, and even operate small applications. mIRC scripts are stored in plain text files (.mrc) or as INI files. With the aid of com scripts and dlls mIRC can be used to automate just about everything in the Windows environment.

History

mSL was developed by Khaled Mardam-Bey since 1996 as a simple scripting language that could work seamlessly with IRC.
