LMS3270
Affordable Mainframe Training and Access
A Mainframe learning environment for beginners to advanced programmers. ​
​
We provide hands-on access for you to learn the skills and technologies used by Mainframe programmers around the world. Learn how to build reliable, scalable, production-ready business applications using the COBOL programming language.
Use your 3270 PC-terminal to Logon and create your own Batch and CICS applications with interfaces to DB2, CICS and MQ. Use various programming tools like TSO, ISPF, the Editor, and more to compile and run your code and Utilities like sorting files. Create files and libraries used to store source code, Job Control Language (JCL), COBOL Copy books and many other types of files. Use DB2 tools and utilities like SPUFI to run SQL and create tables or select data. Create your own CICS Applications from scratch with interactive screens and interface to DB2.

Course Outline
We are not a traditional eLearning Center. We don’t require that you read long boring books and then pass some silly tests to move on. As a programmer, we trust that you have a natural curiosity and passion for learning – we don’t want to mess with that. That's why we focus on the “The Important Stuff”. Our goal is to get you started coding quickly and build from there.
​
With that said, programming is more than just coding. In the mainframe world you’ll need to learn many different skills. While we provide the basics, we also provide full guides with all the details and topics for you to explore and practice at your pace.
Connectivty
3270, TSO/ISPF, CICS
A great beginner’s topic on mainframe connectivity. We explain how to configure 3270 terminal software to logon and access TSO and CICS. We also describe how to use Program Function Keys (PF Keys) and special Attention Keys used to control ISPF and CICS screens.
ISPF
Screen Navigation, Editor, Tools
TSO/ISPF
After our short tutorial on ISPF you can start navigating screens and using tools like a pro. Learn how to:
-
create and manage files
-
use the text editor
-
submit Jobs and view output
-
access DB2 resources with Spufi
-
access MQ resources
JCL & Utilities
Syntax, DD's, JES, SDSF, Sort, IDCAMS
Take our short tutorial on concepts and key terms to pass any job interview. Then follow our learning path to build up your understanding and skills. We’ll take you from basic batch job submission and JCL syntax, to understanding and running Procedures that Compile, link and execute your code. Our topics include:
-
Overview of the JCL Language
