Specifying the JCL statements

Generally, the minimum partition or region for running AMBLIST is 64 kilobytes for all functions except LISTLPA, which requires 100 kilobytes. However, for large load modules, IBM® recommends a minimum region size of 200 kilobytes. For program objects, IBM recommends a minimum region size of 12 megabytes.

AMBLIST requires the following JCL statements:
JOB
Initiates the job.
EXEC PGM=AMBLIST
Calls for the processing of AMBLIST.
SYSPRINT DD
Defines the message data set.
Anyname DD
Defines an input data set. This statement may define a z/OS® UNIX System Services file. If so, the complete path name, including the file name, must be specified. For an object module in a z/OS UNIX System Services file, PATHOPTS=(ORDONLY) must be specified. This statement cannot define a concatenated data set.
SYSIN DD
Defines the data set (in the input stream) that contains AMBLIST control statements.
