Online Programming with CA TELON

Course Objectives
Whilst covering the basics of On-Line CA-TELON programming and how it is used, this Course also aims to give an insight into structuring CA-TELON programs, data access and the data group, validation, screen definitions, CA-TELON list programs and custom code. On completion of this Course the student will be able to:

• Develop structured CA-TELON On-Line Programs
• Develop screen based programs using the PI, PD and SD
• Understand and use the CA-TELON Prototyping Facility
• Understand and use the different validation methods within CA-TELON - field level validation, cross-field edits and segment edits
• Understand and use the Data Group
• Understand and use AUTOEXECs and USEREXECs
• Customise the generated data access
• Understand and develop SEGLOOP programs
• Understand and use the various custom code points within a CA-TELON program
• Understand and manipulate CA-TELON generated variables

PROGRAM TESTING

INTERTEST, XPEDITER or CA-TELON Test Facility

Course Environment Development will be performed using:

• IBM Mainframe
• CA-TELON
• COBOL or PL/1
• CICS or IMS
• DB2, DL/1 or VSAM

Course Format: Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will gain experience of writing and testing different types of CA-TELON On-Line programs using the various program structures available. Examples are used extensively, ranging from simple code snippets to full applications with complete 'real world' functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and 'experiment' with these under the instructor's guidance as they are introduced. These examples are available to take away, along with the delegate's own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
