VisualAge 2000: Facilitating Find and Fix in an OS/390 Environment

Vast numbers of otherwise fully functional application programs are currently unable to interpret the abbreviated date values they contain as belonging to any century but the twentieth. The need to approach the daunting task of identifying, analyzing, and eliminating this limitation in a systematic and efficient manner has led IBM to offer a complementary assortment of products and services collectively known as VisualAge 2000. The guidelines, products, and services that constitute VisualAge 2000 are intended to support customers in their own efforts to tackle the problems posed by the use of abbreviated date fields in their application programs.

This book examines two of the products available in the VisualAge 2000 collection designed to address the requirements of system programmers and application developers engaged in identifying and correcting abridged date fields in their application programs in an OS/390 environment:
Maintenance 2000
Assists in Year 2000 impact analysis of host applications.

The Millennium Language Extensions to COBOL for OS/390 & VM
Provides automatic century windowing for specified date fields.

In addition to providing an introduction to the functionality available within Maintenance 2000, this book uses a sample application as the basis for a concrete demonstration of how the product can be used to perform the tasks of date identification, Year 2000 impact analysis, and result management. The actual results of the Year 2000 impact analysis process are then used as the basis for the correction of date-related problems in the sample application programs using the new facilities of the COBOL compiler known collectively as the Millennium Language Extensions. Three specific approaches to the solution of date-sensitive problems in the sample application programs are presented in order to show how the new enhancements to the COBOL compiler can be used to assist in a gradual and incremental process of date field expansion in your application inventory.

The process of taking the results provided by Maintenance 2000 and applying the corresponding fixes to the application programs by means of the Millennium Language Extensions can be further automated by using
COBOL and CICS Command Level Conversion Aid Version 2.1
COBOL and CICS Command Level Conversion Aid is a tool that can assist with conversion from earlier levels of COBOL. Its primary function is to convert source programs from COBOL 68 or 74 Standard to COBOL 85 Standard. An additional function of COBOL and CICS Command Level Conversion Aid is the ability to add Millennium Language Extensions syntax to the source program. This function is known as the DATE FORMAT conversion option and requires specific input that can be provided by a tool like Maintenance 2000.

Because COBOL and CICS Command Level Conversion Aid represents an important link between Maintenance 2000 and the Millennium Language Extensions this book also provides an introduction to the DATE FORMAT conversion option. However, since the main functionality of the tool is not specifically related to Year 2000, COBOL and CICS Command Level Conversion Aid is not being discussed in its entirety.
