Most systems have a way to find objects when a specific path is not specified. The same is true of the AS/400 and it uses an object called the AS/400 library list (*LIBL). This object doesn't exist on its own and is always associated with another object like a job or a job description (*JOBD). As of OS/400 V5R1 the user portion of the Library List can contain up to 250 library names. Prior to that it could only have 25 libraries. (This is something to keep in mind when selling software because on OS/400 V4R5 and below a job description with more than 25 libraries in its library list cannot be restored.) A job's library list consists of four sections: * System portion: Always at the top and contains AS/400 system libraries like QSYS, QHLPSYS, QUSRSYS, etc. The system portion can hold up to 15 library library names and is specified in the QSYSLIBL AS/400 system value. It can be changed locally using the CHGSYSLIBL AS/400 Command Language. * Product portion: When a AS/400 Command Language is executed that specifies a production AS/400 library that library will be added to the product portion of the library list for the duration of the AS/400 Command Language. It follows the system portion and the O/S will maintain up to two libraries in it. * Current library: Is a special AS/400 library associated with a user profile and there can only one in the list at a time. This library is useful for programmers to have their personal library at the top of the list regardless of what the user portion is changed to. It can be changed locally using the CHGCURLIB AS/400 Command Language. To change it for the user on all future jobs use the CHGUSRPRF AS/400 Command Language. * User portion: The last part of the library list that contains all of the application AS/400 library. The list is normally assigned to the job from the job description but for batch jobs this can be overridden using the SBMJOB command's INLLIBL parameter. A job's library list can be changed locally with the EDTLIBL, CHGLIBL, ADDLIBLE, and RMVLIBLE AS/400 Command Language. As was mentioned above the user portion of the library list for any job can be stored in a job description so that when a job starts up it will use the list specified there. Some job descriptions specify the special value *SYSVAL which means that the library list can be found in the AS/400 system value QUSRLIBL. Please note that if AS/400 library is deleted that is also specified in a job description or either of the library list system values the system will let allow it and all future jobs that use these now tainted lists will fail to start.
