        !             6: .I minterm
        !             7: file format consists of at least one binary valued function
        !             8: definition.
        !             9: A function definition begins
        !            10: .B .o

        !            18: .B .o
        !            19: is a numeric symbol of the function
        !            20: (usually an output pin number of a rom or pal integrated circuit).
        !            21: Any other
        !            22: .IR n 's
        !            23: are numeric symbols of input binary variables.
        !            24: .I Term
        !            25: and
        !            26: .I mask
        !            27: are decimal numbers.
        !            28: .PP
        !            29: There is a correspondence between the bits of the numbers in binary
        !            30: representation and the input symbols, the first input symbol
        !            31: is associated with the least significant bit.
        !            32: The meaning of a bit with value 1 in
        !            33: .I mask
        !            34: is `do care',
        !            35: and the meaning of a bit with value 1 in
        !            36: .I term
        !            37: is `input must be 1'.
        !            38: Thus the
        !            39: .IR term : mask
        !            40: is a implicant, and a set of them when
        !            41: .IR or 'ed
        !            42: together
        !            43: describes the input conditions for which the output symbol will have
        !            44: a value of 1.
        !            45: .PP
        !            46: For example:
