Area3DPtg: Title: Area 3D Ptg - 3D referecnce (Sheet + Area)
AreaPtg: Specifies a rectangular area of cells A1:A4 for instance.
AttrPtg: "Special Attributes" This seems to be a Misc Stuff and Junk record.
BoolPtg: Boolean (boolean) Stores a (java) boolean value in a formula.
ConcatPtg

MultiplyPtg: Implements the standard mathmatical multiplication - *
NamePtg
NameXPtg
NotEqualPtg: Ptg class to implement not equal
NumberPtg: Number Stores a floating point value in a formula value stored in a 8 byte field using IEEE notation
OperationPtg: defines a Ptg that is an operation instead of an operand
ParenthesisPtg: While formula tokens are stored in RPN order and thus do not need parenthesis for precedence reasons, Parenthesis tokens ARE written to ensure that user entered parenthesis are displayed as-is on reading back Avik Sengupta <lists@aviksengupta.com> Andrew C.
