Course overview
Acquire advanced Pathway application programming skills such as cursor control, shadow byte processing, and terminal redisplay. Also included in this 4-day course are topics such as User Conversion routines, intelligent device support (IDS), PATHSEND, and unsolicited message processing (UMP). Through classroom discussion and valuable hands-on experience on the HP NonStop server, you will become proficient in application programming within the Pathway environment. Most of the concepts presented in this course utilize techniques implemented in SCREEN COBOL; however, a few of the concepts also implement programs written outside the Pathway environment and communicate with the Pathway components Terminal Control Process (TCP) or server classes. The course uses COBOL85 as the host language for applying the concepts.
