Generate I/O Program Non-Relational Data Access for COBOL |

Introduction
The UTGENRIO utility program runs on a Windows System with Micro Focus Enterprise Developer and generates programs (COBOL Source Code) that may be used to access non-relational data files and VSAM data sets. The generated programs may be compiled and executed on a distributed Linux, UNIX or Windows (LUW) platform with Micro Focus or an IBM Mainframe System.
Note: This utility program is available under our Controlled Release Program. It requires the installation of a SIMOTIME Enterprise License.
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 the IVP's
The Installation Verification Programs (IVP's) are intended to be used to varify the proper installation and configuration of the SIMOTIME Technologies that are required to generate COBOL source code that accesses non-relational data files and VSAM Data Sets.
IVP-01, 80/80 Copy
The following CMD file (IVP4IOW1.cmd) defines a job that will execute the generated program that does a simple copy of a sequential file with 80-byte, fixed-length records.

Generate a COBOL I/O Program
WIP2
PCF Member, the Record Structure
The Process Control File (PCF) is an ASCII/Text file that contains statements (or Records) that will be used to generate the COBOL source code that will be used to access files or VSAM Data Sets. Each statement that is used in the generation process is identified by a "/" in position 1. Positions 2-10 contain a alpha-numeric text string that identifies the statement type. Position 11 must contain a space character. Positions 12-256 contain additional keywords and values based on the statement type.
| 1. | /SET - This statement is used to define variables that will be used in the generation process. |
| 1.1. |
FILE - This keyword is used to define the basic file specifications. The following is an example of a /SET Statement that is used for file definitions. /SET FILE SYSUT1 org=Sequential recfm=FIXED rlen=80 access=sequential |
| 1.1.1. | SYSxxxx - where xxxx is UT1-UT10, this keyword identifies the default DD name for a file. |
| 1.1.2. | NAME= - this keyword and parameter identifies the User DD Name that will override the SYSxxxx value when a program is generated. |
| 1.1.3. | ORG= - Defines the Data Set organization. |
| 1.1.4. | RECFM= - Defines the Record Format |
| 1.1.5. | RLEN= - Defines the Record Length for files with RECFM=FIXED |
| 1.1.6. | RMIN= - Defines the Minimum Record Length for files with RECFM=VARIABLE |
| 1.1.7. | RMAX= - Defines the Maximum Record Length for files with RECFM=VARIABLE |
| 1.1.8. | ACCESS= - Defines the access mode, the value is SEQUENTIAL or RANDOM. |
| 1.2. | AKEY - |
| 2. | /STCBLID - Used to create the Identification Division of a COBOL source member. |
| 2.1. |
TAG - This keyword is used to define the start of the IDENTIFICATION DIVISION for the COBOL source member being generated. The following is an example of a /STCBLID Statement./STCBLID TAG |
| 3. | /STCBLED - Used to create the Environment Division of a COBOL source member. |
| 3.1. |
The following is an example of the /STCBLED Statements./STCBLED IO=Y |
| 3.2. | IO=Y - This keyword is used to define the start of the ENVIRONMENT DIVISION for the COBOL source member being generated. |
| 3.3. | SELECT - This keyword is used to create a SELECT statement in the ENVIRONMENT DIVISION of the COBOL source member being generated. |
| 3.3.1. | SYSxxxx - This keyword must specify a default DD name that was defined in a preceding /SET statement. |
| 4. | /STCBLDD - Used to create the DATA Division of a COBOL source member. |
| 5. | WIP |
| 6. | /STCBLPD - Used to create the Procedure Division of a COBOL source member. |
| 7. | WIP |
| 8. | /SYSIN - Used to include or insert user statements into the generated program. The user-defined statements may be instream within the PCF member or an external member. |
| 8.1. |
The following statement defines the start of the instream data. /SYSIN * Statements following the preceding statement will be copied to the output file. |
| 8.2. |
The following statement defines the end of the instream data. /SYSIN /* |
| 9. | WIP |
Summary
The UTGENRIO utility program runs on a Windows System with Micro Focus Enterprise Developer and generates programs (COBOL Source Code) that may be used to access non-relational data files and VSAM data sets. This document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.
In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.

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
