Data which does not pertain to a particular section is kept in module level sections which have binder-generated names.

Section 1 (X'0000001') contains the sole elements of classes B_IDRB and B_MAP. It also contains PR and ER ESD records for symbols which are not the target of any adcon.

Section 3 (X'0000003') contains the ESD items (parts) which map the MRG text classes. Examples are B_PRV (the PL/I pseudoregister vector table) and C_WSA (writable static which is used for data items in reentrant C or C++ programs). Although the parts comprising a MRG class may come in from different input sections, the entire class will be mapped as a single element under the appropriate class name in section 3. In addition to the ESDs, section 3 contains any initialization data for the parts in these classes.
