MVS Converter / Interpreter Text Processing z/OS MVS Installation Exits SA23-1381-00 |

Topics Appear as Follows:
The processing of a job control language (JCL) statement includes the stage of converting the JCL statement to C/I text, a form of data that the job entry subsystem (JES) and the job scheduler function of MVS™ both recognize. The converter takes the job's JCL, merges it with JCL from a procedure library, and converts the composite JCL into C/I text. The converter scans each JCL statement for syntax errors and issues appropriate error messages. The converter also resolves symbolic parameters and assigns default values. The converter / interpreter (C/I) text is further interpreted to build the necessary control blocks needed before the job can be scheduled for execution. See the JES2 exit, Exit 6 (converter/interpreter text scan) in z/OS JES2 Installation Exits, and the JES3 exit, IATUX03 (examine/modify converter/interpreter text created for JCL) in z/OS JES3 Customization for more information. |
