SLEEP or WAIT State Micro Focus COBOL Environment |

Introduction
When a job is submitted to a JES Region (or Server) within Micro Focus Enterprise Server to run batch jobs (i.e. submit JCL) it is sometimes a requirement to wait and monitor the results of an asynchronous process. This example will focus on Micro Focus Enterprise Server and the Mainframe Sub-System (or ES/MSS) and the use of a WAIT (or SLEEP) function. This function will cause a delay in processing for the amount of time specifed by the user.
The programs in this example are expected to run in a Micro Focus Enterprise Server and Mainframe Sub-System environment. The callable WAIT Routine is specifically coded for the Micro Focus environment.
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.

Prepare
This section describes the simple tasks required to compile the sample programs. This suite of sample programs contains two COBOL programs and one COBOL copy file. The first COBOL program (CBWAITC1.cbl) is a test program that will call the WAIT or SLEEP routine (MFWAITER.cbl). A COBOL copy file defines the pass area or programming interface that is used for the passing or sharing of information between the COBOL programs or the JCL and the COBOL wait routine. Two directives files are used to document and define the compiler options (or directives).
The COBOL Copy File
The following (PAWAITER.cpy) is the source code for the COBOL Copy File that is used by CBWAITC1 to call MFWAITER.

Mainframe Dialect for Test Program
The COBOL Test program (CBWAITC1.cbl) is a program that will call the WAIT or SLEEP routine (MFWAITER.cbl). It is coded to be mainframe compliant and the use of the OS390 (or later) dialect is recommended and supported for execution in a Micro Focus environment.

Execute and Review
This section describes the JCL Member to test the configuration of Enterprise Server and the Configuration File and the expected results.
JCL Members
Two JCL Members are supplied with this suite of sample programs. The first job will execute a test programs that determines the wait time and calls the wait routine. The second JCL member uses the PARM= function to define the wait time and executes the wait routine direction from the EXEC statement.
COBOL Program, Call the SLEEP Routine
This JCL Member (CBWAITJ1.jcl) will execute a COBOL program that calls the wait routine. The wait time is based on a value specified within the calling program.

This JCL Member (CBWAITJ2.jcl) will execute the wait routine. The wait time is based on a value specified using the PARM= keyword on the EXEC statement of the JCL member.

Two JCL Members are supplied with this suite of sample programs. The first job will execute a test programs that determines the wait time and calls the wait routine. The second JCL member uses the PARM= function to define the wait time and executes the wait routine direction from the EXEC statement.

This example executes a COBOL Test Program (PGM=CBWAITC1) that determines a WAIT (SLEEP or DELAY) time of five (5) seconds and calls a WAIT Routine.

Summary
This example will focus on Micro Focus Enterprise Server and the Mainframe Sub-System (or ES/MSS) and the use of a WAIT (or SLEEP) function. 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.
