This suite of programs will scan JCL members and extract file information based on the IDCAMS or DD statements. The file information will be written to a sequential file. This capability and the information it provides is quite useful when migrating a batch application and data from a Mainframe System to a Windows System using Micro Focus technologies.
The sequential file created by this suite of programs is in the format that is required to do a batch update to the File Properties Repository (a Micro Focus Key-Sequenced-Data-Set or Indexed File). For more information about how to do this refer to the File Properties and Repository Management document.
The source code, data sets and documentation are provided in a single zipped file called JCSCAN01.ZIP. This zipped file may be downloaded from the SimoTime Web site. This example illustrates the following functions.

This section describes the process for scanning JCL Members, PROC's and/or Parameter Control Cards to extract file information fron DD statements and the DEFINE statements of IDCAMS.
This job (JCSCANE1.CMD) is a three step job. The 1st step will do housekeeping to prepare the environment. The second step will delete any files left over from a previous run. The third step will create an ASCII/Text file containing a list of member names to be scanned.
C:\SimoSam1\LOADLIB>JCSCANE1
This job (JCSCANE2.CMD) is a three step job. The 1st step will do housekeeping to prepare the environment. The second step will delete any files left over from a previous run. The third step will scan the source members based on the list of member names and create a record sequential file containing information extracted from DD statements and DEFINE statements for IDCAMS.
C:\SimoSam1\LOADLIB>JCSCANE2
Once the File Information has been obtained from the JCL Scan the record sequential file is in a format that will feed the File Properties Repository Management System. Refer to the Catalog Population for Micro Focus and the File Properties Repository Management provided in separate documents.
The following COBOL copy file (FPMASTB1.CMD) shows the record layout for the record sequential (RSEQ) file that is used to do a batch update of the File Properties Repository.

This section will focus on the COBOL programs.
This program will read the JCSCANL2 file that is a list of source members and/or parameter files (PARM CARDS) and for each record it will set an environment variable for the member name and then call JCSCANC2 to process (or scan) each member.
This program will read a source member, usually JCL, PROC or Parm Card, and produce an output containing data file properties from the DD and IDCAMS information.
