Associated data
The assembler can produce an associated data file that contains
information about the source program and the assembly environment.
The ADATA information includes information such as:
- Data sets used by the assembler
- Program source statements
- Macros used by the assembler
- Program symbols
- Program object code
- Assembly error messages
Different subsets of this information are needed by various consumers, such as configuration managers, debuggers, librarians, metrics collectors, and many more.
