DM is an actively used programming language created in 1994. DM is a programming language for the creation of multi-user worlds. By `world' I mean a virtual multi-media environment where people assume personae through which they interact with one another and computer-controlled objects. This could take the form of a competitive game, a role-playing adventure, a discussion board, or something we haven't even imagined.

Example code from the web:
mob verb smile() world << "[usr] grins." giggle() world << "[usr] giggles." cry() world << "[usr] cries \his heart out."
Example code from Linguist:
// This is a single line comment. /* This is a multi-line comment */ // Pre-processor keywords #define PI 3.1415 #if PI == 4 #define G 5 #elif PI == 3 #define I 6 #else #define K 7 #endif var/GlobalCounter = 0 var/const/CONST_VARIABLE = 2 var/list/MyList = list("anything", 1, new /datum/entity) var/list/EmptyList // creates a list of 99 null entries var/list/NullList = null /* Entity Class */ /datum/entity var/name = "Entity" var/number = 0 /datum/entity/proc/myFunction() world.log << "Entity has called myFunction" /datum/entity/New() number = GlobalCounter++ /* Unit Class, Extends from Entity */ /datum/entity/unit name = "Unit" /datum/entity/unit/New() ..() // calls the parent's proc; equal to super() and base() in other languages number = rand(1, 99) /datum/entity/unit/myFunction() world.log << "Unit has overriden and called myFunction" // Global Function /proc/ReverseList(var/list/input) var/list/output = list() for(var/i = input.len; i >= 1; i--) // IMPORTANT: List Arrays count from 1. output += input[i] // "+= x" is ".Add(x)" return output // Bitflags /proc/DoStuff() var/bitflag = 0 bitflag |= 8 return bitflag /proc/DoOtherStuff() var/bitflag = 65535 // 16 bits is the maximum amount bitflag &= ~8 return bitflag // Logic /proc/DoNothing() var/pi = PI if(pi == 4) world.log << "PI is 4" else if(pi == CONST_VARIABLE) world.log << "PI is [CONST_VARIABLE]!" else world.log << "PI is approximety [pi]" #undef PI // Undefine PI
