changed by the introduction of parenthesis.
lift = lift - 0.2
The Integer or Real point 'lift' is assigned the value calculated by the current
value of point 'lift' minus 0.2.
distance = distance * time
The Integer or Real point 'distance' is assigned the value calculated by the
current value of point 'distance' multiplied by point 'time'.
