STJQUERY, What It Does
The STJQUERY program will make a call to a Micro Focus routine that will provide information about the current job environment based on the user specifications in the JCL being processed.
STJQUERY, How To Use
The following shows a snippet of COBOL source code that is used to call the Job Query Program.
move 'JOBINFO ' to MVS-REQUEST
call 'STJQUERY' using MVS-JOBSTEP-INFO
if MVS-RESPOND = ZERO
perform DISPLAY-JOB-INFORMATION
else
move 'ERROR, ACTION-GET-JOB-INFORMATION' to MESSAGE-TEXT
perform Z-POST-MESSAGE-TO-SYSOUT
end-if
Use the following link to view a sample job that will describe and demonstrate how to use the Job Query Program.

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.
