The first time you log on the AS/400 you will be forced to change your password before continuing.
- Press <Enter>to change your password.
- At the “Current Password” field, type your current password. NOTE: nothing you type on this screen will be displayed to ensure that no one views your password as you type it.
- Press <Tab>or <Field Exit>.
- For the “New Password” field, type the password you would like to use when you sign on to the computer. It must not exceed 10 characters, it must begin with an alphabetic character and the remaining characters may be any combination of alphabetic, numeric characters. Note: Try not to make it too difficult, you will need to know it to sign on the AS/400 again.
- Press <Tab>or <Field Exit>
- At the “New Password (to verify)” field, type in your new password for a second time to make sure you have entered it correctly. If you have entered it incorrectly you will get an error message and your initial password will still be as before.
- Press <Enter>
- Upon completion, the following message will be displayed:
Password changed successfully
- Read the following screens, pressing <Enter>to exit each one, until you reach the AS/400 Main Menu screen.
Later on when you want to change your password, type CHGPWD on the command line and go through the same steps.

The AS/400 Control Language (CL) is a scripting language for the IBM AS/400 midrange 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. CL can also be used to create CL programs (congruent to shell scripts) where there are additional commands that provide program-like functionality (GOTO, IF/ELSE, variable declaration, file input, etc.)
The vast majority of AS/400 commands 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.
Made up of three-character words
Control Language (CL), an integral part of OS/400, is a set of commands by which users control operations and request system-related functions on the AS/400. 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. The command WRKSYSSTS, therefore, is translated as Work with the System Status. CL commands can be entered on the command line or executed from within a program. When commands are entered via a program or menu, the user selects options that are displayed in more friendly, English-type format. The program then translates the selected option into the appropriate CL command or commands.
The conventions for naming the combination verb and object commands are as follows:
The primary convention (as just shown) is to use three letters from each word in the descriptive command name to form the abbreviated command name that is recognized by the system.
The secondary convention is to use single letters from the ending word or words in the command title for the end of the command name, such as the three single letters DLO on the DLTDLO (Delete Document Library Object) command.
An occasional convention is to use single letters in the middle of the command name (usually between commonly used three-character verbs and objects), such as the letters CL in the CRTCLPGM (Create CL Program) command.
Some command names consist of the verb only, such as the MOV (Move) command, or an object only, such as the DATA (Data) command.
The AS/400 is a popular family of mid-sized computer systems which can also be used as multiuser computer systems. By this, we mean that a single computer can interact with more than one user at a time. It was first introduced byon June 21st, 1988.
The AS/400 can be utilized for different business facets. Some models are designed as systems that provide resources to other computers, also known as a “server” in a network of computers, while others are set up for use with terminals or “display stations”. OS400 is the operating system for the AS/400. The AS/400 computers offer more compatibility across the product line than the earlier System/3X computers. Hence, the earlier IBM models of the System/36 and System/38 have since been replaced by the AS/400 systems.
IBM has sold over 600,000 AS/400’s and over 350,000 of them are still active. From distribution warehouses to hospital administrators, and even manufacturing companies, the AS/400 is a strong component in aiding these companies’ daily business operations. The AS/400 utilizes a green screen interface, a built in database that resembles DB2, and a vast array of software to provide business solutions for today’s business needs.
In October of 2000, IBM rebranded the AS/400 and announced its name as theiSeries. As part of IBM’s Systems branding initiative in 2006, it was again renamed to System i. The codename of the AS/400 project was “Silver Lake”, named for the lake in downtown , where development of the system took place.
In April 2008, IBM announced its integration with the System p platform. The unified product line is called IBMand features support for the IBM i (previously known as i5/OS or OS/400), AIX and GNU/Linux operating systems.
It include an integrated DB2 database management system, a menu-driven interface, multi-user support, non-programmable terminals (IBM 5250) and printers, security, communications, client–server and web-based applications. Much of the software necessary to run the IBM System i is included and integrated into the base operating system.
The IBM System i also supports common client–server systems such as ODBC and JDBC for accessing its database from client software such as Java,and others.
Programming languages available for the AS/400 include RPG, assembly language, C, C++, Pascal, Java, EGL, Perl, Smalltalk, COBOL, SQL, BASIC, PHP, PL/I, Python and REXX. Severalare available: AllFusion Plex (see *Plex Wiki), Accelerator for IBM i, ADELIA, Synon, AS/SET, IBM Rational Business Developer Extension, LANSA, ProGen Plus and .
The ILE (Integrated Language Environment) programming environment allows programs from ILE compatible languages (C, C++, COBOL, RPG, Fortran, and CL), to be bound into the same executable and call procedures written in any of the other ILE languages.
The IBM System i fully supports the, including a 32-bit (JVM) and a 64-bit JVM.
