"In my day to day work, I have come across very little on our IBM [zSeries] I can't
do using SELCOPY, particularly for any data or file manipulation, and we will
commonly use it rather than other programming languages.
We use SELCOPY extensively as part of our standard processes for checking
inputs/outputs, data/file manipulation & conversion and producing reports.
In fact, virtually anything for which most people would use one of the legacy
programming languages. We find SELCOPY easy to use for both developing new,
and changing existing, routines and find it saves us significant effort in not
having to compile every time we need to implement a change. Like any other programming
language, the key to successful and simple maintenance is the use of extensive
logic and detailed comments which SELCOPY allows with great flexibility."

Selcopy is used by many
blue chip companies
worldwide, its popularity due
in no small part to its simplicity of use combined
with fast and powerful data handling. Ideal as a
"quick fix" mechanism for repairing data files, or
as a component of a major production suite,
SELCOPY is widely used throughout the Information
Services industry.
Support for iSeries, Unix and PC platforms was
introduced in the late 1990s.
With extra syntax and functionality included in
every new release, SELCOPY has grown to become a
very powerful batch utility language in which to
develop new applications, much easier to code than
compiled languages such as COBOL, PL1 and C++, but
executing at comparible speeds.
SELCOPY syntax is common across all operating
systems on which it is supported, so the same job
may be ported across platforms with little or no
change to the control statements. For example, an
application can be developed under CMS, TSO or
even on a PC, for subsequent operational use in a
z/OS batch environment.
In 2004, all SELCOPY licences for the IBM
mainframe were upgraded to include the use of
CBLi
(CBL's Interactive environment), at no extra cost,
providing the user with a full-screen 3270
windowed environment for running SELCOPY
interactively.
SELCOPY Interactive aids the development and
debugging of applications by allowing the user to
step through the individual SELCOPY control
statements one at a time in order to monitor
changes to program variables and storage.
Also included with CBLi is a richly functioned
file editor, together with various dataset
management tools.
