Application Porting
 Many
legacy mainframe applications were written many years ago in languages such as COBOL,
PL/1, Assembler, FORTRAN, REXX; applications using ISPF/PDF, CICS, IMS and other old
systems. These applications are often very difficult to manage, maintain and support.
There comes a time when your legacy applications
become unmanageable and the only solution is to convert them to a different platform and
technology.
Our
consultants have a great deal of experience with MVS and VM and with legacy programming
languages and systems. We can assist you with conversion of your legacy application to new
Client/Server or Intranet based applications.
In
the framework of a Year2000 project our company successfully converted a Mainframe
application written in PL1 based on VSAM to Delphi using ORACLE database for British
Columbia Government organization.
We
can also help you to incorporate the old legacy system as "black boxes" into new
applications using a variety of programming interfaces.
There are only a few available alternatives and we
are very familiar with all of them:
| • |
Batch interfaces: New
systems can interface with the old ones using some sort of intermediate files or
databases; |
| • |
3270 EHLLAPI: Interfaces to old systems
are based on a programmed terminal emulation of an operator using a 3270 terminal |
| • |
Intermediate Servers:
Building a mainframe interface with a legacy application on one side and the new
application on the other side. The interface to the new system can be based on SNA APPC
technology or the TCP/IP-based sockets API, or other higher level communications
technology. |
We
will be happy to help you with conversion of your legacy systems to modern applications.
