This suite of programs will create and populate the QSAM files and VSAM data sets used by many of the sample programs provided by SimoTime.
This example illustrates the following functions.
| 1. | How to create and populate a QSAM file using mainframe JCL. | |
| 2. | How to create a VSAM, KSDS (Keyed Sequential Data Set) data set using mainframe JCL and IDCAMS. | |
| 3. | How to populate a VSAM, KSDS data set using mainframe JCL and a COBOL program. | |
| 4. | How to delete a VSAM, KSDS data set using mainframe JCL and IDCAMS. |
The source code, data sets and documentation are provided in a single zipped file called UTLDAT01.ZIP. This zipped file may be downloaded from the SimoTime Web site. The file names have file extensions. When uploaded to the mainframe from the PC the file extension is dropped.
Many of the sample programs access a a QSAM or sequential file. This file is created by running an MVS batch job using a single mainframe JCL member.

The member name is QSMCRTJ1.JCL. The first step in the job executes IEFBR14 with a DD statement that has a DISP=(MOD,DELETE,DELETE). This step will delete a previously created file with the same name.

The second step in the job executes IEBGENER. The data for populating the QSAM file is contained within the JCL member. The inline data will add 26 records to the file in alphabetic sequence by customer number. The following table contains detailed information about the file.
Item Description PC file name QSAM0080.DAT Fully Qualified MVS name SIMOTIME.DATA.QSAM0080 DD Name QSAM0080 Record Format Fixed, Blocked Record Length 80 with 800 character block length Position Description 01-06 Customer Number 07-07 filler 08-27 Last Name 28-37 First Name 38-62 Street Address 63-78 City 79-80 State Code
The preceding job may be executed on the mainframe as an MVS batch job. It may also be executed on the PC running Micro Focus Mainframe Express product. The JOB and DD statements will require modification prior to execution on a mainframe.
Creating and populating the VSAM, KSDS data set is a two step process. The first step runs the KSDCRTJ1.JCL member that executes IDCAMS. This will create an empty VSAM data set.

The preceding is an example of the mainframe JCL (KSDCRTJ1.JCL) needed to create a catalog entry for a VSAM data set.
The preceding mainframe job will just create a catalog entry. There are no records in the file. The following section provides an example of one method that may be used to populate the VSAM, KSDS data set.
To populate the VSAM data set requires mainframe JCL and a COBOL program. The approach used in this example will read a QSAM file and update or add records in the VSAM data set.

The following JCL (QSMDELJ1.JCL) uses IEFBR14 and a DD statement to delete a QSAM file.

The preceding job may be executed on the mainframe as an MVS batch job. The JOB and DD statements will require modification prior to execution in different mainframe environments. The job may also be executed on the PC running the Micro Focus Mainframe Express product.
This section describes how to delete a VSAM Keyed-Sequential-Data-Set (KSDS). A VSAM, KSDS may be date-protected. The DEFINE Cluster has the option of specifying a retention date. If this retention date has not expired then the PURGE option will be required in order to delete the data set. The default is NOPURGE
The standard operation by the VSAM DELETE is to delete the catalog entry of the cluster and mark the space used by the cluster as reclaimable. The data contents of the cluster is no longer generally available but the data is still present until the area is reused. This introduces a potential problem or security exposure for sensitive data. The information could be retrieved using some special class of DUMP/RESTORE utilities that are often used by data center staff. The ERASE function will write over the data area used by the cluster and the original data is destroyed. The default is NOERASE.
The following JCL (KSDDELJ1.JCL) uses IDCAMS to delete a VSAM Data Set.

This document provides a quick summary of the File Status Key for VSAM data sets and QSAM files.
The SimoZAPS Utility Program has the capability of generating a COBOL program that will do the conversion of sequential and VSAM (KSDS) files between EBCDIC and ASCII. SimoZAPS can also read a sequential file in EBCDIC format and create an ASCII/CRLF file or VSAM KSDS file in ASCII format. The conversion tables may be viewed or modified to meet unique requirements.
The following is a list of sample conversion programs created by the GENERATE function of SimoZAPS.
| Program | Description |
| cble2a01 | Convert from an EBCDIC-Sequential file to an ASCII-Sequential file. This example includes a mainframe JCL member. |
| zap00101 | Convert from an EBCDIC-Sequential file to an ASCII-Text file. |
| zap00201 | Convert from an EBCDIC-Sequential file to an ASCII-Indexed file (Sequential-Add). |
| zap00301 | Convert from an EBCDIC-Sequential file to an ASCII-Sequential file. |
| zap00401 | Convert from an ASCII-Text file to an EBCDIC-Indexed file (Sequential-Add). |
| zap00501 | Convert from an ASCII-Text file to an EBCDIC-Indexed file (Random-Add). |
