Specifying selected NC variables

The selected NC variables are specified via the DB9910 data block (selected NC variable).
The length of the data block depends on the number of NC variables selected in the variables
list. The variables list can contain maximum 42 selected NC variables. The DB9910 data block
contains the data for variable addressing and data type conversion for each NC variable.
