For the new statistic/systematic switches the concept of independent/master/slave has been introduced. The components have special dialog boxes. The user can select the switch type in a combo box. This will also enable the possible input fields and change the number of nodes (slave switch has 4 nodes). The distribution for the statistical switch takes into account the specification of the IDIST parameter on the miscellaneous switch card (ATP|Settings/Switch). Selecting IDIST=1 will disable the Distribution group and force Uniform distribution.
