Writing an operating system/2 application

This paper illustrates use of the key facilities of Operating SystemlTY (OSITY). It provides some guid-ance on how to use the interfaces and functions imple-mented by the system and then introduces the pro-gram development environment. Two examples demon-strate the use of some of the more interesting capabili-ties. The paper discusses many of the significant differ-ences between the functions of OS12 and those of the Disk Operating System (00s).
