Introduction
(Next) (Previous) (Table-of-Contents)

This suite of programs will describe how to submit a second job to the internal reader or INTRDR from within the currently running job using a COBOL program. For this example the second job (or submitted job) simply executes IEFBR14 with a return to the caller.

The source code, data sets and documentation are provided in a single zipped file called CBLSUB01.ZIP. This zipped file may be downloaded from the SimoTime Web site. In the Windows environment the file names have file extensions. If the JCL member is uploaded to a ZOS Mainframe from the Windows and Micro Focus environment the file extension is dropped.

Example 01, Simple Job Submit
(Next) (Previous) (Table-of-Contents)

This example contains two (2) JCL members. The first JCL member executes a COBOL program that will submit a job to the internal reader.

The second JCL member uses IEFBR14 to return to caller and is submitted by the COBOL program being executed by the first job.

Example 01, JCL Member to Submit a Job to the Internal Reader
(Next) (Previous) (Table-of-Contents)

The following mainframe JCL (CBLSUBJ1.JCL) executes a COBOL program that will submit a job to the Internal Reader. The COBOL program is coded to read an 80-byte record sequential file (JCLINPUT) and write to an 80-byte record sequential file (SUBTORDR). The COBOL program is a simply file copy. The DD statements map the COBOL file names to the actual physical locations. The file to be copied is JCLINPUT and the output file is SUBTORDR. The JCLINPUT file is member of a partitioned data set (PDS) that contains JCL. The SUBTORDR file is mapped to SYSOUT=(,INTRDR) and is copies the JCLINPUT to the internal reader (or submitts the job to the internal reader).

Example 01, Sample COBOL Program
(Next) (Previous) (Table-of-Contents)

The following COBOL program (CBLSUBC1.CBL) will submit a job to the Internal Reader. The COBOL program is coded to read an 80-byte record sequential file (JCLINPUT) and write to an 80-byte record sequential file (SUBTORDR). The COBOL program is a simply file copy. The DD statements in the JCL map the COBOL file names to the actual physical locations. The file to be copied is JCLINPUT and the output file is SUBTORDR. The JCLINPUT file is member of a partitioned data set (PDS) that contains JCL. The SUBTORDR file is mapped to SYSOUT=(,INTRDR) and this copies the JCLINPUT to the internal reader (or submitts the job to the internal reader).

Example 02, Job Submit & Modify JCL
(Next) (Previous) (Table-of-Contents)

This example contains two (2) JCL members. The first JCL member executes a COBOL program that will submit a job to the internal reader. The JCL (or source code for the JOB script) will be modified prior to submission.

The second JCL member uses IEFBR14 to return to caller and is submitted by the COBOL program being executed by the first job.

Example 02, JCL Member to Submit a Job to the Internal Reader
(Next) (Previous) (Table-of-Contents)

The following mainframe JCL (CBLSUBJ2.JCL) executes a COBOL program that will submit a job to the Internal Reader. The COBOL program is coded to read an 80-byte record sequential file (JCLINPUT) and write to an 80-byte record sequential file (SUBTORDR). The COBOL program is a simply file copy. The DD statements map the COBOL file names to the actual physical locations. The file to be copied is JCLINPUT and the output file is SUBTORDR. The JCLINPUT file is member of a partitioned data set (PDS) that contains JCL. The SUBTORDR file is mapped to SYSOUT=(*,INTRDR) and is copies the JCLINPUT to the internal reader (or submitts the job to the internal reader).

Example 02, Sample COBOL Program
(Next) (Previous) (Table-of-Contents)

The following COBOL program (CBLSUBC2.CBL) will submit a job to the Internal Reader. The COBOL program is coded to read an 80-byte record sequential file (JCLINPUT) and write to an 80-byte record sequential file (SUBTORDR). The COBOL program is a simply file copy. The DD statements in the JCL map the COBOL file names to the actual physical locations. The file to be copied is JCLINPUT and the output file is SUBTORDR. The JCLINPUT file is member of a partitioned data set (PDS) that contains JCL. The SUBTORDR file is mapped to SYSOUT=(*,INTRDR) and this copies the JCLINPUT to the internal reader (or submits the job to the internal reader).

The following program will scan the JCL records looking for the CLASS= text string based on the PARM= data passed from JCL. The CLASS will be changed accoeding to the information in the PARM= parameter.
