Special Requirements
This section will describe programs and techniques that may be considered a bit esoteric but are quite often in the critical path within an application.
Assembler, non-Executable Member
In the CICS environment on the mainframe it was a common practice to use the EXEC CICS LOAD function to load a data table into memory. These data tables were typically created as mainframe assembler source members. The source members were then compiled and linked as non-Executable load members.
This example will describe how to create a non-executable load member from Assembler Source Code for the Micro Focus Studio and Server environments running in EBCDIC or ASCII.
Extract FCT Entries from DFHDRDAT
The resource used by the Micro Focus Enterprise Server, Mainframe Subsystem Support (or ES/MSS) is stored in the resource definitions file (DFHDRDAT). This file is a Micro Focus Key-Sequenced-Data-Set. This utility program provides a batch access to get the FCT information and post this information into an ASCII/Text file.

Submit JCL to INTRDR from CICS
This example uses a COBOL program running under CICS to submit a job (i.e. JCL) to the Internal Reader (or INTRDR). The program uses command level CICS statements (EXEC CICS SPOOL) to access the internal reader. The program will run on an IBM Mainframe System with CICS or a Microsoft Windows System with Micro Focus Server and the Mainframe Sub-System option.

Summary
The purpose of this document is to assist as a tutorial for new programmers or as a quick reference for experienced programmers that are interested in supporting an application that is dependent on the mainframe CICS architecture. Links to additional documents, programming examples and services are provided.
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
