This paper proposes a high-level scripting language, which can be used to express workflow for scientific and engineering tasks running on Computing Grid. Since it is difficult for common computing users to explore the grid computing resource successfully without computer-experts’ help; it is feasible that computing users should be presented an easy-study-and-use language to express their workflow and it is up to computer-expert to realize an interpreter to translate the scripting-language file into XML scripting language file. Furthermore, this destination file should conform to specification of BPEL4WS such that the prototype system realized will hold good expansibility.
