MIRC scripting language
The mIRC scripting language is used with the mIRC client for the IRC chatting protocol. It is able to perform automated actions with regard to that program, such as for the setting up of "bots". Its syntax uses blocks with curly braces (similar to C and a number of other languages), but doesn't separate statements with semicolons as many languages do.
Files commonly use the .mrc extension (which might be confused with unrelated MRC microscope images or Mixed Raster Content images), but can also use a .ini extension when they are intended to initialize the settings of mIRC.
