Kevin was not trying to persuade. He was merely stating facts. The number of pages is not the relevant part of the information. The relevant limitation is the number of bytes that a halfword can support. Aside from the BLKSIZE point, we would not consider a number about 32767 (for example 65528) as the limit, for compatibility reasons. There are surely programs that use "LH" on the 2-byte length field without subsequently clearing the high bytes and then rely on the value that would misbehave if they land with a negative number.
