MOD 30ML Functions
DISPLAY BLOCK
17. Display state names can appear in any expression, where they are treated as long state
variables, but they cannot be the target of an assignment. Display states are identified
by number in the instrument and are assigned numbers, starting at 1, in the order in
which they appear in the display scripts.
DSPSTATE is a local attribute whose value represents the current display state. It can
appear in any expression.
To change display state, DSPSTATE is assigned a value. Typically, DSPSTATE is
assigned a user defined display state name:
DSPSTATE = HEAT;
Another typical use of DSPSTATE is to change to the "next" state:
DSPSTATE = DSPSTATE + 1;
