LIMIT commands for a variable area criterion.
Question: Given the following criteria how would I write a limit command to satisfy the equation ?
     An area under each righting arm curve up to the angle of maximum      righting arm of not less than the area determined by the following      equation: A = 10.3 + 0.187 (30-Y) at max RA.
Answer:
It takes two consecutive LIMIT commands to handle this criterion:      LIMIT(1) AREA FROM 0 TO MAX AT 15 > 13.1 LIMIT(2) AREA FROM 0 TO MAX AT 30 > 10.3      These are mentioned in the manual under the LIMIT command in the Command Dictionary.      Syntax Notes: 1) These two limits must be consecutive; e.g. 1 & 2 as above. 2) The /LIMIT:COMBINE subparameter must also be used on any RA command where the two limits are to be evaluated as a single varying limit. The interpretation is that the limit value is 13.1 when the angle of MAX is at 15°, 10.3 when it is at 30° and a linear interpolation between 13.1 and 10.3 when it is between these angles.
