Detailed description
2.2 Userdefined auxiliary functions
2.2.3 Extension of predefined auxiliary functions
Function
Because there is only one set of machine data for the predefined auxiliary functions, they
can only ever be used to address one spindle of the channel. To address further spindles,
user-defined auxiliary functions must be parameterized to supplement the predefined
auxiliary functions.
Extension of predefined auxiliary functions refers to the "address extensions" parameter. The
number of the spindle that the auxiliary function refers to is entered in the "address
extension" parameter.
The relevant predefined auxiliary functions can be extended for the following system
functions.
