CORE. For example, programs that access the system date may require the COBOL/3. Y2. K compliant. In many examples the programs are coded to the ANSII'8. The Hexadecimal notation is a COBOL II syntax and is also part of the ANSI/2. The programs will also work with COBOL for MVS, COBOL/3. COBOL/3. 90. A few programs use Micro Focus syntax and are documented as such and will not run on the mainframe. These programs are intended for a Linux, UNIX or Windows platform running Micro Focus (or microfocus) COBOL. JCL members are provided to run the batch jobs as MVS (or ZOS) batch jobs on an IBM Mainframe System or as a project with Micro Focus Mainframe Express (MFE) running on a PC with Windows. For more information about Micro Focus refer to http: //www. Micro Focus Enterprise Server provides the foundation platform (or sub- system) that allows applications that are currently running on a Mainframe System with ZOS to be copied (at the source code level) to a Linux, UNIX or Windows System and then compiled and executed. Refer to. http: //www. Also, the sample programs may be compiled using Micro Focus Net Express running on Windows. In the Net Express environment adjustments for the ASCII environment, the mapping of the COBOL file names to the PC file names. The replacement of JCL with BAT or CMD files is optional. Today, our primary system of choice for individual programmers and unit testing is Windows/7. Pointers In Cobol Programs SamplesOur primary Quality Assurance Testing (QAT) and Production environment is Windows Server/2. In the early 2. 00. Micro Focus delivered Enterprise Server and Studio (Server is for production deployment and Studio is for the development environment). This technology provided companies with the ability to move batch and online applications between a Mainframe System and a Linux, UNIX and Windows System. Reply to: data movement using pointers in COBOL: Hi Guys, Thanks for the information. Introduction This suite of programs will describe how to use procedure pointers and external data items. A procedure pointer will be defined in a primary COBOL (or. ILE COBOL Programming Considerations. This section has the following chapters: Working with Data Items; Calling and Sharing Data Between ILE COBOL Programs. The process of moving and preparing the applications requires the Micro Focus Server or Studio to be installed and configured. The application source code is moved and compiled on the target platform. The application is now ready for unit testing. Most of the COBOL programs may also be compiled and executed on a Linux, UNIX or AS/4. System. Simo. Time does not formally test all of the sample programs in these environments. However, we do have customers that have used many of the sample programs in these environments. Many of the applications (sometimes referred to as Legacy Applications) running on IBM Mainframes are written in COBOL and have been providing mission critical business information for ten years or longer. Some applications or parts of an application were written over twenty- five years ago. The mainframe continues to be the largest, single platform running applications that leverage the use of the COBOL language. However, it is important to note that COBOL source code that adheres to the ANSI'8. UNIX system. Once downloaded it may be compiled and executed on a personal computer or a UNIX system. Is there anything like pointers cannot be passed among cobol programs? Am new to this pointer concept in Cobol programming and in my project trying to send a Character pointer from C program to Cobol. The advantages and disadvantages of the proliferation, maintenance or replacement of COBOL applications are not discussed. The COBOL Connection uses a simple value proposition - Legacy Applications, longevity based on continued business value. 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 intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources. Copyright . The COBOL programs are written using the COBOL/2 or COBOL/3. COBOL for MVS, COBOL/3. COBOL/3. 90. The date and logging routines require COBOL/3. Y2. K compliant. Simply click on one of the following items for more information. Link Tag. Description. SIMOMODS.

On the IBM Mainframe the Customer Master File is a VSAM Keyed Sequential Data Set (referred to as KSDS). On a Windows or UNIX System using Micro Focus the Customer Master File is an Indexed File or Key Sequenced File. The Customer Master file contains variable length records with the minimum and average record length being the same length of 5. The key starts in the first position of the record and is 1. The record layout is defined in a COBOL copy file and contains text strings and various numeric formats including zoned- decimal, packed and binary. This program suite provides an example of how to create and populate a Customer Master File. On the Mainframe System the file is a VSAM, Key- Sequenced- Data- Set (or KSDS). On a Windows or UNIX System the Micro Focus Indexed File format is used. The file contains 5. Review the Documentation for this suite of program members. On a Windows or UNIX System using Micro Focus the Item Master File is an Indexed File or Key Sequenced File. The Item Master file contains variable length records with the minimum and average record length being the same length of 5.

The key starts in the first position of the record and is 1. The record layout is defined in a COBOL copy file and contains text strings and various numeric formats including zoned- decimal, packed and binary. This program suite provides an example of how to create and populate the Item Master File. On the Mainframe System the file is a VSAM, Key- Sequenced- Data- Set (or KSDS). On a Windows or UNIX System the Micro Focus Indexed File format is used. The file contains 5. Review the Documentation for this suite of program members. Since that time the specifications for COBOL have evolved, expanded and improved. The following is an overview of the popular COBOL dialects. Also, a link for downloading or accessing detailed information is provided. Bit manipulation is usually considered something that cannot be done using COBOL. This is an example of how COBOL can do bit- level manipulation. Both COBOL programs are written using the COBOL/2 dialect but also work with COBOL for MVS and COBOL/3. Review the Documentation for this suite of program members. The example shows simple conversion between upper and lower case plus capitalization and editing of specific words within a text string. Both COBOL programs were written and tested using the VS COBOL II dialect. Also, both COBOL programs will work with COBOL for MVS and COBOL/3. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or as a project with Micro Focus Mainframe Express (MFE) running on a PC with Windows. Also, a CMD member is provided to run the job with Micro Focus Net Express (MFE) running on a PC with Windows. Review the Documentation for this suite of program members. A procedure pointer will be defined in a primary (or mainline) program. The procedure pointer will then be used to call a secondary program. A linkage section will not be required in the secondary program since the data will be accessed (or shared) using external data items. Both COBOL programs are written using the COBOL/3. COBOL for MVS and COBOL/3. Review the Documentation for this suite of program members. Mainframe System with ZOS) but fail in an ASCII environment (i.
