Migrating from the RM/COBOL Environment
We advise that you carry out the following steps to ensure successful
migration from the RM/COBOL environment to this COBOL environment:
1. Transfer all your source programs and their associated data files
to the target machine.
2. If your source programs contain any TAB characters, run the tabx
program to expand them into a form that is acceptable to this
COBOL system. See the section The Tabx Program later in this
chapter for details.
3. If you wish to submit your source programs to this COBOL system in
batch mode, you must create a command file containing the commands
needed to do this. See your operating system documentation for
details of the format of the command file. See your COBOL System
Reference for full details of the commands needed to submit your
source programs to this COBOL system.
4. Submit your source programs to this COBOL system. The command to
do this is specific to your implementation. See your COBOL System
Reference for full details.
5. Investigate the cause of any problems you may experience when you
submit your source programs to this COBOL system. The chapter
RM/COBOL Conversion Problem Solving describes known problems which
you may experience and gives hints on how you can recover if you
receive them. Resubmit your corrected source programs to this
COBOL system.
6. Test any sections of your source programs which do not use data
files. If you receive unexpected results see the chapter RM/COBOL
Conversion Problem Solving for a description of known problems you
may experience in executing your source programs, and hints on how
to correct these. Alternatively, use the debugging tool,
Animator, to isolate and correct any problems.
7. Ensure the ACCEPT/DISPLAY module ADIS
is configured correctly. See your COBOL System Reference for
details.
8. Run Convert3 to convert any existing data files used by your
source programs to a format that is acceptable to this COBOL
system. See the chapters Converting RM/COBOL Data Files, Running
Convert3 and Using the File Conversion Program for full details on
how to use Convert3.
9. Finish system testing.
10. Archive your original data files to disk or tape.
If disk space on your system is limited you may not be able to have both
the old and the new copies of all your data files present on your system
at the same time. If this is the case, load and unload the data files
gradually onto your system during the conversion process.
