Introduction
One of the popular numeric formats used on a Mainframe System and in the COBOL programming environment is the Zoned-Decimal format. In the COBOL environment this format is defined by specifying the "USAGE IS DISPLAY" clause. Since this is the default format for COBOL it is rarely hard-coded and quite often the programmers forget about its physical structure and the advantages and disadvantages of using this numeric format.
One of the advantages of using this numeric format is the ease at which it may be displayed or printed and read by human beings.
One of the disadvantages of this format is its sensitivity to content. If a non-numeric value is placed in this field and an arithmetic operation is attempted a system error occurs and this causes an abnormal termination of the program.
The following sections of this document will use examples to show how to manage a situation where non-numeric values (such as high-values or X'FF') are intentionally placed in a Zoned-Decimal field and then properly managed to obtain the desired business result.
We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Data Input and Output
The following sections describe the data flow and format.
Data Input, EBCDIC-encoded File
The input is an EBCDIC-encoded, record sequential file containing 80-byte, fixed-length records. The first 17 bytes of the last record in the file are X'FF' or high-values. The first 10 bytes of the record structure are defined as PIC X fields. Bytes 11-17 are defined as PIC 9 fields. This technique can cause problems if the application program tries to use the numeric (PIC 9) fields for an arithmetic operation. On the mainframe this could result in a S0C7 Program check. On a Micro Focus platform it could result in an RTS 163 message with an abnormal termination of the program.
Also, during a conversion between EBCDIC and ASCII-encoding care may need be taken to ensure the High-Values are not converted between X'FF' and X'9F'.
The following is a Hexadecimal Dump of the EBCDIC-encoded test file. The RED line represent the ASCII-encoded characters. The 1st GREEN line represents bits 0-3 of a hex-dump byte, the 2nd GREEN line represents bits 4-7 of a hex-dump byte. The BLUE line representes the EBCDIC-encoded characters.

Data Output, ASCII-encoded File
The output is an ASCII-encoded, record sequential file containing 80-byte, fixed-length records.
The following is a Hexadecimal Dump of the ASCII-encoded test file. The RED line represent the ASCII-encoded characters. The 1st GREEN line represents bits 0-3 of a hex-dump byte, the 2nd GREEN line represents bits 4-7 of a hex-dump byte. The BLUE line representes the EBCDIC-encoded characters.

Technical Details
This section provides additional details about the programs and control files that are used in this suite of programs.
USAGE IS DISPLAY Field
This document will focus on a discussion of a numeric field (or data string) format referred to as Zoned-Decimal and is commonly used on an IBM Mainframe System. This is the default numeric format for COBOL and may be explicitly defined with the "USAGE IS DISPLAY" clause.
The "SIGNED, ZONED-DECIMAL" format has caused problems for years for mainframe programmers because the signed position of the field will display as a character value of "A-I" for positive numbers and "J-R" for negative numbers. It also allows for a positive and negative zero value that will display as a "{" and "}", this is the curly brace symbol or x'C0' and x'D0'.
When converting this type of field from EBCDIC to ASCII the programmer is presented with a number of confusing options and challenges. This document will try to explain the options and help the programmer avoid the common mistakes that are made during a conversion process.
Explore The Zoned-Decimal format for numeric data strings. This numeric structure is the default numeric for COBOL and may be explicitly defined with the "USAGE IS DISPLAY" clause.
Compiler Options or Directives
The following link provides a guideline for using Micro Focus compiler directives based on the application environment and data access requirements.

Generated Conversion Programs
The COBOL programs in this example are generated using the SimoTime Enterprise Technologies for Application and Data Migrations. The generation technology uses a COBOL copy file for a definition of the record structure and a Process Control File to define and control the structure and behavior of the generated programs.

The following (NBRXFFC1.cbl) is the main COBOL I/O program that does the file I/O and makes a call to the routine that does the record content conversion between EBCDIC and ASCII.

Company Overview
SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.
Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.
Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.
Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
