A Job step parallel execution control system in a computer system has a job control statement which can designate whether a job step is to be executed by a specifically designated host computer or by a arbitrarily selected host computer, whether parallel execution of the job step while other job step in the same job is in execution, and/or whether the job is to be continued, to be forcedly terminated or to be terminated after termination of the other job step of the job currently in execution, upon commanding execution of the job step. Upon execution of the job, the job control statement is sequentially decoded to efficiently control parallel execution and termination of execution of the job step.
