The numbered items in the following list correspond to the numbers in the Ref column in the above table.

1. This is equivalent to the PM1 field RLD_TYPE. A new RLD type added in PM2, type 21, which is used to address the origin of any loaded class segment.
2. Name of the class containing the adcon. For PM1 program objects, RLD_CLASS is set to B_TEXT.
3. Module and section offset have been replaced with the offset relative to the start of the class and element, respectively.
4. New PM2 field. Is initialized to zero unless otherwise noted.
5. The 8-bit PM1 direction flag is reduced to a single bind flag in PM2.
6. For A- and V-type adcons (types 10 & 20), RLD_NAME_SPACE=1. For Q-type adcons (type 30), RLD_NAME_SPACE=2. Otherwise, RLD_NAME_SPACE=0.
