Device specific commands

GameMaker also has the possibility to start external programs. There are two functions available for this: execute_program and execute_ shell. The function execute_program starts a program, possibly with some arguments. It can wait for the program to finish (pausing the game) or continue the game. The function execute_shell opens a file. This can be any file for which some association is defined, e.g. an html-file, a word file, etc. Or it can be a program. It cannot wait for completion so the game will continue.
