You use a text editor to create the OpenTP1 system definition files. Note the following about creating the definition files:

• Use the Shift JIS encoding for the definition files.
• Make sure that each line in the definition files ends with an end-of-line code. Some text editors do not automatically insert an EOF control character at the end of a file. In such a case, the definition specified on the last line of the definition file might not be recognized.

You can use the dcdefchk command to check the created system definitions.

For details about the system definitions and checking the definitions, see the manual OpenTP1 Version 7 System Definition.
