Remote Edit/Compile/Debug
The applications for this scenario can be
CICS, batch, TSO, or IMS/TM (running under BTS). Applications can
access DB2, VSAM, DL/I, QSAM, and virtually any other form of data.
Examine the distribution of the tasks
between the host and workstation, the benefits of this scenario,
and the costs to set it up.

Which Tasks are Done Where "X" indicates the primary platform for the task |
Task | Host | WrkS |
Edit programs on the workstation.
The program files are transparently retrieved
from and saved to the host. This includes the source, JCL, and held
job SYSOUT. The source remains on the host. |
| X |
Compile the programs.
Compilations to create load modules are done on the host but
initiated from the workstation via MVS job submission.
You can also perform a syntax check of your source files on the workstation
with the source on the host; COPY files are retrieved from the host.
Neither DB2 nor CICS is required on the workstation for the syntax checking.
|
X | |
Test and debug the compiled programs.
Execution takes place on the host. Batch
execution is initiated from and controlled from
the workstation (CICS transactions must be started from a 3270
emulator session). The debugger runs cooperatively
with a GUI on the workstation and the engine on the
host. |

Notes |
|
Benefits |
- Be more productive with your editing tasks with
the language-sensitive VisualAge COBOL editor.
It parses the source as you enter it, giving a
visual presentation. The learning curve is not as
steep as you might think: the editor is customizable and can
be made to look and feel like your favorite
editor while retaining all the strengths of a
workstation editor.
- Save time: compile-time error messages appear right in your edit
session following the line on which the error occurred.
- Reduce the number of compile jobs you have to submit by
using the VisualAge COBOL's ANALYZE option to easily
perform syntax check compiles on the workstation,
shaking out syntax errors before submitting
compiles to the host compiler.
- Reduce the number of batch debugging jobs and ease your debugging tasks by
using a GUI on the workstation
even when your program is executing
on the target host - interactively.
- Use your existing jobs for system test
with the benefit of workstation organization.
- Use this scenario no matter what kind of data your program accesses,
even for your applications that include COBOL calling or being
called by Assembler programs.
- Host programmers get an easy start on becoming familiar with the workstation environment.
|
Costs |
- Host systems programmers need to be involved for configuration of the communications.
- Network traffic will increase.
