Each bit of the first element shows the state of the corresponding alarm named in
ST1NAME; the odd elements show the first 16 elements of ST1NAME, the even show
the last four. Similarly for the remaining pairs with ST2NAME etc.

4-element enumerated array
A list of variable names, each element having the same list.
None
Contains the variable names for the control module to use in the secondary variable

The variable SVNAME shares data with this variable. When a selection is made in
SVNAME, it causes the control module to use the contents of the equivalent
enumeration in SVCONT as the value to be displayed on the auxiliary line of the single
analyzer display screen. Element 1 is displayed on line 1, and so on. The description in
SVNAME is used as the text description on the variable line on the same screen.
