We can host this training at your preferred location. Contact us!

Designed, written and presented by Minerva Douglas, one of the UK's foremost IMS programming specialists, this course teaches the skills and techniques required to write programmes in both IMS/DB and IMS/TM (formerly IMS/DC) environments.
The course covers not only IMS database access, but also includes the programming components necessary for coding on-line programs.
The course contains several practical exercises that allow attendees to work through various programs and learn the most structured and efficient use of IMS database calls.

This course is also available 'On Demand' at the High Wycombe training centre, or for one-company, on-site presentations.

COBOL or PL/I programming experience and program edit and submission knowledge.

  • describe the basic components of IMS DB (DL/I) and IMS/TM
  • understand and use the terminology encountered in IMS environments
  • describe and explain the main facilities available in IMS DB
  • code and test a basic COBOL or PL/I program to access IMS databases
  • write a typical Message Processing Program
  • describe the differences in conversational programs
  • write and test a simple PSB
  • use BTS to test an MPP
  • recognise simple MFS statements.
