Packed Field with Spaces Usage is COMP-3 (Packed Decimal) |

Introduction
This document (with sample programs) describes the anomalies of working with packed numeric fields that contain spaces. For the COBOL programming language these fields would be defined as COMPUTATIONAL-3 or COMP-3.
This suite of programs will build test data and discuss techniques for managing packed numeric fields and displaying a field in a hexadecimal dump format. Allowing a space character (or any non-numeric value) to exist in a packed-decimal field should be considered as a bad programming practice. The process that causes this to happen should be identified and corrected.
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.

Execute
This suite of programs incudes a group of CMD files and a JCL members to map the file names and execute the programs that accumulate the Summary Totals and Record Counts. The output is posted to the SYSOUT device.
CMD File, Execute Program
The following command files will process a test file that contains records with packed-decimal field that contain space characters. The records contain packed-decimal fields that have both EBCDIC and ASCII encoded space characters. Each job will read the records in the test file and accumulate summary totals for each of the packed-decimal fields in the record structure. Each job uses a different methodology for handling the spaces in the packed-decimal fields.
CMD, HEX20 & HEX40 is DISABLE
The following (NBRPK3W1.cmd) is a sample of the Windows CMD needed to run this job with Windows and Micro Focus COBOL. The function to test for spaces in a packed-numeric and treat as a zero value is disabled for this job.

Review the Results
The output created by the programs are summary totals for each of the packed-decimal fields in the test data file. At End-of-Job (EOJ) the programs will write the summary totals to the SYSOUT device. For the Micro Focus environment the programs were compiled using the OUTDD directive with SYSOUT specified as a line sequential (or ASCII-Text) file with a record length of 121 bytes. Therefore, the output may be easily viewed using a text editor of choice.
This section will describe the outputs based on various settings of the HEX20 and HEX40 functions.
Results, HEX20 & HEX40 is DISABLE
The following shows the results when a packed-decimal field contains space characters. The test data for the following report contained three (3) records. The records contain packed-decimal fields that have both EBCDIC and ASCII encoded space characters.
The programs that are used to produce the following report simply attempt to use the values in the packed fields to accumulate summary totals. The programs were first compiled with the default compiler options/directives for a mainframe environment. Refer to the Default Compiler Directives section of this document for the Micro Focus Compiler directives. When an attempt was made to process one of the fields that contained all space characters an ABEND or Program Check resulted with an error message that indicated the field contained a non-numeric value (for the ZOS environment this would be a S0C7 error, for Micro Focus it would be an RTS 163 error).
Next, the programs were compiled with compiler options/directives that would prevent the ABEND. Refer to the Alternate Compiler Directives for NBRPK3R1 section of this document for the Micro Focus Compiler directives. When an attempt is made to process one of the packed-decimal fields that contained all space characters the sign position is corrected and the program check does not occur. However, since an ASCII space (x'20') or an EBCDIC space (x'40') are valid numbers this will result in the summary totals being incorrect.
The following shows a report that was created with HEX20 and HEX40 set to DISABLE. The test file contained three (3) records with both EBCDIC and ASCII spaces in some of the packed-decimal fields. For example, in the 1st record NBRPK3B1-FIELD-01 contains a valid numeric value of 123. In the 2nd and 3rd records NBRPK3B1-FIELD-01 contains ASCII space characters.
Typically, a business user would expect the spaces to be treated as zeroes and the summary total to be 123. However, this is not the case with packed-decimal fields. Using the SIGN-FIXUP directive avoids the S0C7 or RTS 163 error but the ASCII space characters are treated as valid numbers and result in a value of 20202. When reading the three records and accumulating the summary total the result for NBRPK3B1-FIELD-01 is as follows.
123 + 20202 + 20202 = 40,527

Prepare
Prior to executing the jobs it will be necessary to create (or generate) the programs that will read a test file and accumulate totals for the packed-decimal fields. The following is an overview of the programs that will be generated.
| 1. | NBRPK301.pcf - this set of programs will process the packed-decimal fields with the NET20 and NET40 functions disabled. |
| 2. | NBRPK302.pcf - this set of programs will process the packed-decimal fields with the NET20 and NET40 functions set to ZERO_ADJ. The program that accumulates the summary totals will first test the packed-decimal field for all spaces (EBCDIC or ASCII) and if true set the value to zero prior to adding to the summary total. This will produce a summary total that a business user would expect. |
| 3. | NBRPK303.pcf - this set of programs will process the packed-decimal fields with the NET20 and NET40 functions set to ZERO_FIX. The program that accumulates the summary totals will first test the packed-decimal field for all spaces (EBCDIC or ASCII) and if true set the value to zero prior to adding to the summary total and the data file will be updated to reflect the changes. Also, this will produce a summary total that a business user would expect. |

Create Test Data
This section describes the COBOL program that is used to create the test data. The test data is a record sequential file of 80-byte fixed-length records. Each record contains a record ID field and four (4) numeric fields in packed-decimal (COMP-3) format. Some of the packed fields will contain space characters that are invalid and will cause a SOC7 error (non-numeric in numeric field) message. The purpose of this example is to process packed-decimal fields that contain space characters or invalid values.

Technical Details

USAGE IS COMP-3 Field
A packed decimal representation stores two decimal digits in one byte. A packed decimal representation stores decimal digits in each "nibble" of a byte. Each byte has two nibbles, and each nibble is indicated by a hexadecimal digit. For example, the value 23 would be stored in two nibbles, using the hexadecimal digits 2 and 3. The sign indication is dependent on your operating environment. On an IBM mainframe, the sign is indicated by the last nibble of the last byte (or high memory address). For explicitly signed fields the "C" indicates a positive value and "D" indicates a negative value. For unsigned (or implied positive) fields the "F" indicates a positive value.
Explore The Packed-Decimal or COMP-3 format for numeric data strings. This numeric structure is supported by COBOL and may be explicitly defined with the "USAGE IS COMP-3" clause.

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
