The AS/400 Control Language (CL) is a scripting language for the IBM AS/400 mid range platform bearing a resemblance to the IBM Job Control Language and consisting of an ever-expanding set of command objects (*CMD) used to invoke traditional AS/400 programs and/or get help on what those programs do.
A CL command usually is made up of three-character words; up to 10 characters (usually three words) can be merged together to form commands. For example, in CL, work is abbreviated as WRK, system is abbreviated as SYS, and status is abbreviated as STS.
What is a CL Procedure A CL procedure is a group of CL commands that tells the system where to get input, how to process it, and where to place the results. The procedure is assigned a name by which it can then be called by other procedures or bound into a program and called. […]
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 […]
Although most system functions can be invoked directly by using CL commands, it is generally easier for novice users to take menu paths to describe the task to perform and then let the system choose for appropriate command. For example, let’s use the menu path to create a library. If you entered a 4 (for […]
