private FuncPtg()FuncPtgs are defined to be 4 bytes but the actual FuncPtg uses only 2 bytes.
If we have leftOvers that are read from the file we should serialize them back out.
If the leftovers are removed, a prompt "Warning: Data may have been lost occurs in Excel"
//protected byte[] leftOvers = null;
//Required for clone methods
| public FuncPtg(RecordInputStream in)Creates new function pointer from a byte array
usually called while reading an excel file.
//field_1_num_args = data[ offset + 0 ];
field_2_fnc_index = in.readShort();
/*
if (data.length - offset > 2) { //save left overs if there are any
leftOvers = new byte[2];
System.arraycopy(data, offset+1, leftOvers, 0, leftOvers.length);
}
*/

numParams = ( (Integer)functionData[field_2_fnc_index][2]).intValue();
} catch (NullPointerException npe) {
