Parameter transfer

Parameter transfer is implemented using registers.

All the input parameters, plus the return values and return code are specified in a structure (address, length, type).

Apart from explicit types (string, integer and Boolean), it is also possible to specify keywords as input parameters.

For further details, see chapter “Program interfaces”.

Note

The system administration functions can only be called in TPR mode. In all other respects they behave like predefined functions when called.
