      //Required for clone methods
public FuncVarPtg(RecordInputStream in)
Creates new function pointer from a byte array usually called while reading an excel file.

        field_1_num_args = in.readByte();
        field_2_fnc_index  = in.readShort();
public FuncVarPtg(String pName, byte pNumOperands)
Create a function ptg from a string tokenised by the parser

        field_1_num_args = pNumOperands;
        field_2_fnc_index = lookupIndex(pName);
        try{
            returnClass = ( (Byte) functionData[field_2_fnc_index][0]).byteValue();
            paramClass = (byte[]) functionData[field_2_fnc_index][1];

            returnClass = Ptg.CLASS_VALUE;
