All, Set of Allowed Values for each Format, as precise as I can make it. Each of the Formats used by Info, In and InOut parameters define a Set of Allowed Values "Set". The User may select one element of the "Set" to configure a Model or Simulation. Each element of the "Set" consist of a single value or an n-tuple of values. A value is either a single Float, Integer, Boolean, UI, or String. (Value <value>) The "Set" contains one 1-tuple <value>. (Corner <typ> <slow> <fast>) The "Set" consists of three 1-tuples (<typ>, <slow>, <fast>) . (Range <typ> <min> <max>) (Type Integer) The "Set" consists of all integer numbers (1-tuples) between <min> and <max> (inclusive). (Range <typ> <min> <max>) (Type Tap|Float|UI) The "Set" consists of all real numbers (1-tuples) between <min> and <max> (inclusive). (Increment <typ> <min> <max> <delta>) The "Set" consists of the numbers (1-tuples) "<typ>+N*delta" where N is any positive or negative integer such that "typ+N*delta" is between <min> and <max> (inclusive). (Steps <typ> <min> <max> <# steps>) The "Set" consists of the numbers (1-tuples) "<typ>+N*(<max>-<min>)/<# steps>" where N is any positive or negative integer such that "<typ>+N*(< (<max>-<min>)/<# steps>" is between <min> and <max> (inclusive). (Table (..)(..)(..)) ) The "Set" consist of one N-tuple where N=(Number of Rows)*(Number of Columns) (Gaussian <mean> <sigma>) The "Set" consist of one 2-tuple (<mean> <sigma) (DjRn <minDj> <maxDj> <sigma>) The "Set" consist of one 3-tuple (<minDj> <maxDj> <sigma>) (Dual-Dirac <mean> <mean> <sigma>)) The "Set" consist of one 3-tuple (<mean> <mean> <sigma>) Note: In set theory <http://en.wikipedia.org/wiki/Set_theory> , an (ordered) n-tuple is a sequence <http://en.wikipedia.org/wiki/Sequence> (or ordered list) of n elements, where n is a positive integer.
