The COBOL veneer layer is a library used by the precompiled application along with Open Client Client-Library. The COBOL code generated by the precompiler calls functions in the veneer layer, each of which calls a specific Client-Library function. The veneer layer performs conversions and other operations that make it possible for COBOL to communicate with Client-Library. The veneer layer also provides conversions that translate between COBOL host variables and Adaptive Server datatypes.
There are two types of data items: elementary and group data items. The following subsections describe these types of data items.
