• JCL and batch basics: JOB/EXEC/DD statements, return codes, submitting from USS, and reading output

  A JCL job is a JOB statement, one or more EXEC steps each naming a program, and DD statements binding files/datasets to that program's I/O; each step ends with a return code where 0 is clean and higher values signal warnings or errors, and a job can be submitted from the USS shell with submit and its output read through SDSF or the z/OSMF jobs REST API.
