Process programs may change during enactment. The change of an enacting process program should be controlled. This paper describes process program change control in the CSPL (Concurrent Software Process Language) environment, which consists of techniques to (1) define change plans, (2) analyze and handle change impacts, and (3) resume process programs. Moreover, we provide an editor to guide process program change, with which the consistency between a change plan and the actual change can be

If the dependencies among process components are well-specified in a process program, the change control mechanism will detect all the affected components when the process program is changed. CSPL OVERVIEW CSPL is a Unix-based PSEE. It has been ported onto a PC, and will finally be ported onto the Internet. CSPL environment is composed of the CSPL language, a CSPL compiler, a CSPL server, an Object Management System (OMS) server, multiple CSPL clients, and multiple OMS clients. Figure 1 shows the CSPL architecture. The CSPL language is used to develop process programs. The CSPL compiler translates process programs for enactment. During process enactment, the CSPL server interacts with CSPL clients to
