Chapter 5 Using RJE in Programmatic Mode Programmatic control is a feature of RJE that enables it to be a multiuser process. It allows RJE to be run in a mode where many users or application programs, running concurrently with the subsystem, can submit command files to it. RJE processes instructions from these command files as it would process instructions from any command file. Programmatic control operates through use of message files, repeat/interrupt mode and user-written procedures. For information about message files, refer to Appendix B, "Using RJE Files." For a discussion of the message file parameter MSGFILE in the #RJLINE command, refer to Chapter 3, "RJE User Commands." Repeat/Interrupt mode is discussed below and under the #RJOUT command in Chapter 3, "RJE User Commands." For information about the creation and utilization of user-written procedures, refer to Appendix E, "User-written Procedures." This chapter contains the following information on the following topics: * The function of programmatic control * Operating requirements * Setting #RJOUT parameters * Interrupt mode * Use of [CTRL]-Y * Factors to consider when using programmatic control * Examples
