32.2.5.1 Inventory Validation
The Cortex tool cross references the run JCL, the procs, the FCBs and various
includes. Then it cross references the source programs, copy books, macros,
subroutines, PSBs, the CICS tables and maps for CICS; basically all the JCL
elements. In CICS the CICS PPT and transaction programs and applications are
cross referenced. The tool cross references these against the base Processing
Program Table (PPT). From these each element is linked to what the element
includes to determine what is referenced, what is missing and which is
unreferenced. The benefit of the tool is that when you run the Cortex scan utility
the results are available in a few minutes versus a few days if cross referenced
manually.
32.2.5.2 Translate the Languages/Programs
The Cortex MS tool can translate most syntax that is acceptable to VSE
compilers, and most of the clauses that VSE and MVS compilers interpret
differently.
COBOL Conversion Tools
The main support the Cortex MS tool provides regarding COBOL conversion is
with Reserved Words.
Assembler Conversion Tools
The main task the Cortex MS tool provides regarding Assembler conversion is
with Macros.
32.2.5.3 JCL Conversion Tools
Cortex MS converts most VSE JCL and job entry control language (JECL)
statements and operands, and their different formats.
The main tasks the Cortex MS tool provides regarding JCL conversion are:
•
Expand the JCL and convert it in association with the file information that
comes from the programs
•
Provide guidance on file handling
•
Provide the capability for exception handling
32.2.5.4 File Transfer
The Cortex MS tool automatically handles the transfer of most files from VSE to
MVS by building the REPRO jobs to copy the correct files to OS/390. The tool
builds a listing, to be used for data migration, from reading VTOCs and
LISTCATs. It also reads JCL, the programs and the source code from which to
build cross references.
The tool does not provide any utility to transfer the data, only the utilities to
prepare jobs to use IDCAMS. The IDCAMS REPRO standard utilities that exist in
both VSE and OS/390 can provide this function.
