I need call executable files of OS. I see various options, but I´m not sure. I believe don´t understand correctly. I need: -Call executable files from system. -Call associated programs of links, for example, I could pass 'http://google.com'. The result must be open the default browser of user with that link. -Call commands or .BATs files from OS. -I need use that on any OS, must be cross-platform, is very important. If that is not implemented on Pharo, is possible create a .exe file with another language, where I call functions of OS, and invoke from Smalltalk that exe?
