Migrating from the RM/COBOL Environment
You are advised to 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 which expands them into a form that is acceptable to this
COBOL system. See "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. Chapter 7
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 Chapter 7 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 Chapter 8 to Chapter 10 for full details on
how to use convert3.
9. Finish system testing.
10. Archive your original data files to disk or tape.
Note that 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.
