Autocall matching for C370LIB and archive libraries

z/OS MVS Program Management: User's Guide and Reference
SA23-1393-00

C370LIB data sets and archive libraries contain special directory information stored by the EDCLIB procedure and ar command respectively. Recent versions of these programs supply attribute information about the object files in the libraries, and support multiple copies of the same program in a single library with variant attribute informnation.

The binder uses some of the attribute information to choose among the variant object files. In priority order, the binder will attempt to match a called program's attributes with those declared by the caller based on:
  1. 64-bit execution mode
  2. Use of XPLINK linkage
  3. Writable static
