Most of these messages occur when you switch to Composer version 2.1. They can be ignored for the most part.
--Parsing file E:\PROJECT\ANC_CO~2\EBY0884.CLD... Block 9399 S1 integer value 65534 (real value 0.000000) too big for short.
From the picture, you can see that somebody must have put 0.0 in S1 of block 9399 (a real number) instead of 0 (an integer). A real number does not have the same structure as an integer, so DBDOC tells you about it. We do not know if it works, but some errors of this type have found actual problems for clients.
