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 dataset or a z/OS® UNIX System Services pathname.

Use the PATH parameter to specify a z/OS UNIX System Services pathname, and also use the PATHOPTS parameter to be able to access the file for reading. If pathname is a directory name, the filename must be specified on the MEMBER parameter of the AMBLIST control statement. If the pathname ends with the filename, then omit the MEMBER parameter.

SYSIN DD
Defines the data set (in the input stream) that contains AMBLIST control statements.
