You can list all modules in the fixed link pack area, the modified
link pack area, and the pageable link pack area.
To map link pack area modules, invoke AMBLIST with the LISTLPA
control statement. For sample output, see LISTLPA output.
You can also produce a map and cross-reference listing of a nucleus.
To map the contents of the DAT-on nucleus, invoke AMBLIST with
the LISTLOAD MEMBER=IEANUCxx control statement.
Figure 1 shows how to use the LISTLOAD
and LISTLPA control statements to list a system nucleus and map the
fixed link pack area, the modified link pack area, and the pageable
link pack area. Note that in this example the data set containing
the nucleus is named SYS1.NUCLEUS, and the nucleus occupies the member
named IEANUC01. The map no longer represents the IPL version of the
nucleus and message AMB129I will be issued. Use IPCS to format the
NUCMAP. For information on using IPCS, see
z/OS MVS IPCS User's Guide
and
z/OS MVS IPCS Commands.

LISTLPA
/*
- SYSLIB DD Statement
- Defines the input data set, which in this case contains the nucleus.
- SYSIN DD Statement
- Defines the data set containing AMBLIST control statements, which
follows immediately.
- LISTLOAD control statement
- Instructs AMBLIST to format the control and text records including
the external symbol dictionary and relocation dictionary records of
the load module IEANUC01 in the data set defined by the SYSLIB DD
statement. It also specifies a title for each page of output, to be
indented 25 characters from the left margin.
- LISTLPA control statement
- Instructs AMBLIST to map the fixed link pack area (FLPA), the
modified link pack area (MLPA), and the pageable link pack area (PLPA).
