IBM Licensed Programs: Application Development Products
(DFU/AE) support provided within the IBM OS/400 to allow validation of database fields
and additional fields as well as scrolling forward and backward when browsing database
records.
Two additional components in ADTS/400 are:
• File Compose and Merge Utility (FCMU)
FCMU is a compare function that performs a comparison on two or more source physical
files and locates the differences. When synchronization of multiple versions of a source
file is required, the merge function takes the output of the compare and integrates it into
the base file automatically. This can also be done through the interactive session with a
split-screen merge facility similar to the browse and copy split screen in SEU.
• Interactive Source Debugger (ISDB)
ISDB helps in testing and debugging the programs. It is a tool that displays the source of
the program while the program is under the debug mode. Problems and program bugs
can be easily identified by displaying variables and reviewing the source statements.
Interactive Source Debugger speeds debugging and moves the applications into
production faster.
The two features of ADTS/400 are:
• Application Dictionary Services
The IBM Application Dictionary Services feature is a programmer development tool to
assist in program development and maintenance. It is a dictionary on the AS/400 system
that provides references and cross-references of data on the system. It can generate a
complete inventory of all the software components on the AS/400 system, regardless of
programming language. This inventory is stored in the dictionary and can be updated
while an application is being modified.
Application Dictionary Services can analyze impacts due to changes. It provides lists of
files and programs that will be affected by a potential change to a field. This reduces the
time spent in identifying and understanding all of the components of an application.
A synchronization capability, known as the Notify function, allows Application Dictionary
Services to monitor for user domain object changes (create, delete, rename, and so on)
to keep its dictionary and the system synchronized. This is based on a centralized system
facility (the System Audit Journal) that can be set to record any operation on an object in
the user’s domain of the system.
Application Dictionary Services can be accessed from CODE/400.
• Application Development Manager
The IBM Application Development Manager feature provides version control and software
configuration management functions. It allows a group of application developers to create,
manage, and organize multiple versions of their application. The application manager
