INTRODUCTION TO TELON BATCH
COURSE OUTLINE

Tuesday Morning

Instructor Presentation:

Purpose of Telon – Productivity, Standardization, Ease-of-use.
Telon Components – Design Facility (TDF), Generator, Test Facility
TDF Components – Panel Image, Panel Definition, Batch Definition, Program Structure Charts
Review of first program

Lab:

Write and compile a complete Telon program (employee list) from detailed instructions. This segment can also be done as a pre-class assignment by the students with least Telon experience. This will help them to follow the class at a speed which will not bore those who have been struggling with Telon.

Result: The students will have begun to learn how to navigate around the TDF, paint reports, map data from the database to the report, add validation and reformatting rules, access the database, and produce a report, including a brief introduction to the concept of control break and summary groups.

Tuesday Afternoon

Review, Q & A of Previous Session

Instructor Presentation: Telon Test Facility

Lab: Test the program written this morning, using the Test facility to simulate other programs not written yet, and to diagnose errors.

Result: The students will have begun to learn how to test a batch Telon program.

Wednesday Morning

Review, Q & A of previous session

Review compile listing of List Program to tie new Telon concepts to existing COBOL knowledge.

Instructor Presentation:

Writing an update program.
A program designed to show the handling of multiple files/databases, including both AUTOEXEC and USEREXEC.

Lab: Write and test the update program.

Result: Students will now be competent to program file and database I/O.

Wednesday Afternoon

Review, Q & A of previous session

Instructor Presentation:

Control Break Processing.
Control Groups, detail, toppage, etc.
Alternate mapping parameters.
Batch Work Area variables.

Lab: Add the complex report to the update program.

Results: Students will now understand report processing in detail.

Thursday Morning

Review, Q & A of previous session

Instructor Presentation:

The multi-detail Report.
Telon Structure Charts.
Data Groups, Transaction files
Further Details of the interaction between custom code and telon-generated code.

Lab: Complete and test the multi-detail report.

Result: The students will now be competent to build and test simple Telon Batch programs.

Thursday Afternoon

Review, Q & A of previous session

Instructor Presentation: adding an extract file

Lab: Add extra features to the last program, and retest.

Result: This segment creates a more realistic level of complexity in a program. Students are now competent to write any Telon program which does not use the SORT and MERGE features.

Friday Morning

Review, Q & A of previous session

Instructor Presentation: mainline SORT

Lab: Build and test the sort program.

Result: Students are now competent to write any Telon Batch program including a mainline sort.

Friday Afternoon

Review, Q & A of previous session

Review, detailed discussion of compile listing of sort program, demonstrating how each line of code is derived from activities in the TDF.

Instructor Presentation: Match and Merge.

Lab: There is no lab for this session because there would be no opportunity for review.

Result: Students are now fully competent to write any Telon Batch program.
