You can really never run out of bits in the pmap since the pmap is implicitly extended with an infinite number of zero bits. If I count the bits required by the template instructions you posted, I get it to four. So you should proceed as if your pmap was 1100. NULL means that a value is not present and is used for fields that are specified as optional (the attribute presence="optional" in the XML syntax) /David > Hi, I had a datastream for FAST, i started decoding and reached > succesfully upto this point, but after this I got confused.
