2. Discuss the naming conventions used in the structure of CL command names.

3. List and define the 4 parts of a library list and the order in which a search for an object takes place if a simple object name is used.

Explanation / Answer

1. Compare and contrast the 3 methods for issuing CL commands: keyword notation, positional notation, and prompting.
In keyword notation you must input the data in a particular pattern in order to achieve the results that you desire. This pattern is the parameter value immediately followed by the keyword in parentheses.
In positional notation allows you to immediately enter the page of your choosing by simply entering the correct parameters in the command prompt.
In prompting you choose the numerical value of the menu choice that you desire on the screen that you are on. An example of this would be choosing option number 1 on the main menu in order to go to the User Tasks screen.
All three of the CL commands allow you to achieve the particular screen that you desire, however, they all go about it in different ways. Some may be faster than others yet in the end you are able to reach the desired location.

2. Discuss the naming conventions used in the structure of CL command names.
The naming convention that is used in the structure of CL command names attempts to simplify the information for the user who will later attempt to find it. The program does this by taking the information that you may be looking for and filing it under a three letter abbreviation. This usually does not include vowels; however, there are a few outliers to this premise such as LIB.

3. List and define the 4 parts of a library list and the order in which a search for an object takes place if a simple object name is used.

a. System Library List: The shipped system libraries should include the following:

        QSYS—contains essential system objects, such as system programs and commands, as well as pointers    to all other libraries.

        QSYS2—contains additional system programs and files.

        QHLPSYS—contains all the Help information for different screens

b. Product Library -if library is needed for some task a user has requested. For example, if a user requests compilation of an RPG ILE program, the library QRPGLE is inserted as a product library during the compile process and then removed when the process is finished.

c. Current Library List--When objects are created, they are “placed in” (associated with) a library. This association is logical. Unless you specify otherwise, most new objects are placed in the current library, if one is designated for the job. If no current library is designated, a default IBM-supplied user library is used.

d. User Library List - names the libraries that organize the programs, screens, data files, and applications that users need to do business on the system.

The library list is searched in the following order: system library list, product library, current library, and user library list. Individual libraries are searched in the order specified in the library list, from top to bottom.
