transaction in the back end. In
addition to keeping up with the
application-development trends
and evolving tooling features, RDz
expanded its family to include
Rational Development and Test
Environment (RD&T) for System z.
The RDz family and its integration
with the IBM Collaborative
Lifecycle Management solution
play a key role in helping
enterprises implement and adhere
to the best practices of continuous
integration and continuous
testing-necessary steps to enable
companies to adjust to the market
shifts that are pushing for more
frequent and faster time to market.
As an IDE, RDz has evolved
from the standard edit, compile
and debug scenarios to cover
the end-to-end spectrum of the
development lifecycle. The RDz
family helps developers do their
tasks in a productive way while
meeting the enterprise standards
and rapidly evolving technologies.
The various stages of application
development include:

any developer to start his work
is access to the team's software
configuration management
(SCM) system. Most organizations store their source code
in some form of a source code
repository. As an IDE, RDz has
out-of-the-box support to access
Rational Team Concert* (RTC),
CA Endevor, IBM Software Configuration and Library Manager
(SCLM), and also provides a
framework that allows customers to connect their SCMs to RDz.

perception is that developers
spend most of their time
editing code, but in reality,
much time is spent trying to
analyze and understand the
code and its flow. This is even
more cumbersome in the z/OS
world where, over the past 30

to 40 years, the applications
have evolved and are mostly
written in procedural
languages like COBOL, PLI,
etc. The program control flow
and the perform hierarchy/call
hierarchy features in RDz aim
to help application developers
gain faster understanding
of the program flow. The
visual and tree display of the
program logic helps anyone,
experienced or newbie, get

their heads around complex programs easily (see

analysis is complete, it's time for editing. RDz
provides rich COBOL, PL/I and JCL editors with
content assist, real-time validation of the syntax,
formatting, etc. These features are standard in the
distributed application development space, but
for a z/OS application developer, having syntax
errors flagged while typing is a huge productivity
boost. Without this feature, the developer has to
do a compile of some sort and sift through the
listings to fix errors. The capability to edit multiple
