IBM OS/390 Time Clock User Manual


 
functional descriptions of batch applications (standards and
system independent).
EZ-PCL (Easy PCL)
A PC/MS-Windows based graphic user interface (GUI) to the
PDB, which enables definition or modification of batch
applications in their flowchart representation.
PREP (Preparation)
An interactive system of preparation, submission, backout, and
restart of OS/390 jobs.
SWITCH (Switchover)
Transfers VSE files to OS/390 and DFSMS using VSE and
OS/390 file information stored in the PDB.
ENV (Environment)
A set of subroutines supplied in source format that may be
required to simulate VSE functions without an OS/390
equivalent: ISAM, COMREG, UPSI, and so on.
Some of the CORTEX MS/ENV simulation subroutines may be used for execution
of the converted applications. Otherwise, no other CORTEX MS components are
required for OS/390 operations.
Figure 57 illustrates the automated conversion process that can be developed,
using the CORTEX Migration System, to convert VSE applications to OS/390.
Figure 57. Automated Conversion Process
The discussions that follow address the functions provided by mass migration
tools. The tool and process being referred to is the CORTEX MS aid developed
by SISRO and licensed to IBM as the MVS-MS (Migration System).
The key functions provided by the mass conversion tool are:
