AS400 commands are CL (Control Language) commands. Most of them were written by IBM developers to perform system-level tasks like compiling programs, backing up data, changing system configurations, displaying system object details, or deleting them. Commands are not limited to systems-level concerns and can be drafted for user applications as well. A CL command usually […]
To Create Printer output CRTPRTF , a program, OS/400 utility, or print-key function must write the output data to a printer file. A printer file is a type of device file that determines what attributes printed output will have.
Help Screen is a common type of information screen in AS400. it gives Help information about almost any kind of display. Suppose you were going to work with members using PDM (WRKMBRPDM) and were not sure what the parameter, “Member type” meant. you could place the cursor anywhere on the line for that parameter and […]
The current library (*CURLIB) is the first user library that is searched before the rest of the user libraries in the list when the system looks for an object. If a user does not specify a library name when requesting an operation on an object, the libraries in the library list are searched for the […]
The IBM AS/400 provides an integrated set of Application Development Tools (ADT) to design, develop and maintain applications. One such tool is the Programming Development Manager (PDM) that offers the following: Integrated application development environment. List-oriented selection of items for development or maintenance. Extendable interface to tools through user-defined options. Another tool is the Source […]
Programs are created from source statements. On the AS/400, source statements are entered using PDM, the Program Development manager. Technically, PDM uses the Source Entry Utility (SEU) as the editor. But you don’t have to think of SEU as something different from PDM. PDM provides a way to enter program source statements and then to […]
A library list is similar in concept to the “PATH” in Unix and MS-DOS. It specifies which libraries are to be searched and the order in which they are searched when the system looks for an object. A library list is identified by the value *LIBL. A default library list is automatically created by OS/400 […]
