Did you know you could use KILL rather than ENDJOB?

Over the years, many users have assigned their own names to various IBM-provided commands. Historically, they may have duplicated the IBM command to another library, changing the name, or they may have written their own command and command processing program (CPP), which then used the IBM-provided command. These approaches have drawbacks--a major one being that release changes to the IBM commands (new parameters, new parameter values, etc.) would often cause those users to have to also change their instance of the command. With V5R4, IBM provides a much easier way to use your own names for existing commands.
