Both the OpenTP1 administrator and the users who execute operation commands must define environment variables. An OpenTP1 directory to be subject to operation command processing is defined in DCDIR, and a definition storage directory is defined in DCCONFPATH.

The correspondence between an OpenTP1 and an operation command is determined by the defined DCDIR.

Under the examples/tools/ directory, there are sample programs that allow the user to enter operation commands into the specified OpenTP1 without consciousness of OpenTP1 environment variables. For more information about the samples, see the manual OpenTP1 Programming Guide.
