Certain XFD formats, (type 4 and 6 known with certainty) do not provide c-treeRTG enough information to generate a proper SQL mapping of OCCURS DEPENDING ON variable structured data types. c-treeRTG maintains these mappings in a structure termed XDD and provides a utility, xddgen, with limited parsing capabilities to generate this information directly from COBOL source. The xddgen utility has been updated to better handle additional cases of OCCURS DEPENDING ON.
This variable structure now maps into a SQL LONG field if it is the last field of the FD.
