TRUE de couple s the pre s e nt-value prope rty from the
phys ical output. While TRUE, the pre s e nt-value can be
change d to any value to s imulate conditions for te s ting
without affe cting the actual phys ical output.
Valid value s are re al numbe rs in the range 0–100.
Value s gre ate r than 100 are inte rpre te d as 100. Whe n
commande d, value s are writte n to the pre s e nt-value
with a priority for writing, which corre s ponds to a
priority-array inde x (s e e "priority-array" he re in).
An array of prioritize d value s (inde xe s 1-16) controlling
the pre s e nt-value , inde x 1 having the highe s t priority.
The value with the highe s t priority for writing controls
the pre s e nt-value . Pos s ible value s for priority-array
inde xe s are re al value s or NULL. A NULL value
