Processing the prelinker automatic library call

The following hierarchy is used to resolve a referenced and currently undefined symbol.

• The undefined name is an short name, for example SNAME.
  • If the NONCAL command option is in effect, the partitioned data sets that are concatenated to SYSLIB are searched in order as follows:
    • If the data set contains a C370LIB-directory created using the z/OS® XL C/C++ object library utility, and the C370LIB-directory shows that a defined symbol by that name exists, the member of the PDS containing that symbol is read.
    • If the data set does not contain a C370LIB-directory created using the z/OS XL C/C++ object library utility and the reference is not to static external data, the member or alias, with the same name as SNAME is read.
• The undefined name is an long name.
  • If the NONCAL command option is in effect, the partitioned data sets that are concatenated to SYSLIB are searched. If the data set contains a C370LIB-directory created using the z/OS XL C/C++ object library utility, and the C370LIB-directory shows that a defined symbol by that name exists, the member of the PDS indicated as containing that symbol is read.
