Interpreting batch loader output

The batch loader output consists of a collection of diagnostic and error messages and an optional storage map of the loaded program. The output is produced in the data set defined by the SYSLOUT DD and SYSTERM DD statements. If these statements are omitted, no output is produced.

SYSLOUT output includes a heading, and the list of options and defaults requested through the PARM field of the EXEC statement. The SIZE stated is the size obtained, and not necessarily the size requested in the PARM field. Error messages are written when the errors are detected. After processing is complete, an explanation of the error is written. z/OS MVS System Messages, Vol 8 (IEF-IGD) lists the batch loader error messages.

SYSTERM output includes only numbered warning and error messages. These messages are written when the errors are detected. After processing is complete, an explanation of each error is written.

The storage map includes the name and absolute address of each control section and entry point defined in the loaded program. Each map entry marked with an asterisk (*) comes from the data set specified on the SYSLIB DD statement. Two asterisks (**) indicate the entry was found in the link pack area; three asterisks (***) indicate the entry comes from text that was preloaded by a compiler. The TYPE column indicates what each entry on the map is used for: SD=control section, LR=label reference, and PR=pseudoregister.

The map is written as the input to the batch loader is processed, so all map entries appear in the same sequence in which the input ESD items are defined. The total size and storage extent of the loaded program are also included. For PL/I programs, a list is written showing pseudoregisters with their addresses assigned relative to zero. Figure 1 shows an example of a module map. The batch loader issues an informational message when the loaded program terminates abnormally.
