The following describes Figure 1 and Figure 2.

A

Entry Names. For the member, the library (ddname) and member name are displayed, along with the primary entry point offset and AMODE. The MEMBER NAME field contains the primary name.

For each alias or alternate entry point, AMBLIST shows the alias name, entry point offset and AMODE. If no aliases are present, AMBLIST prints NO ALIASES. If the input name is an alias, then its name is printed in the alias section preceded by two asterisks.

The constants ALT PRIMARY will be added to the right of the amode of the alias name which was a long primary name in which the binder had converted to an alias.

B

Attributes of the Module. The attributes of the module are represented by bits. Each bit is set either ON or OFF. In the listing, AMBLIST interprets the bit settings and shows a descriptive value in the STATUS column. For example, in Figure 1 and Figure 2, bit 0 is interpreted as NOT-RENT. This means the module is not reentrant. For a description of all the STATUS values, see Table 1.

C

Other Attributes. The remaining module attributes are displayed following the table. This includes the system status index (SSI) field, the APF (authorized program facility) code, the RMODE (residence mode) for the entire module, the PO format (loader data level), the OS compat level (binder data format), and XPLINK. If attribute bit 19 is the OFF state, NONE will be displayed in place of SSI. SSI is usually set through the SETSSI control statement in the binder or SPZAP programs.

Note: For an OS Compat Level less than z/OS® V1R3, no Compat level will be printed.

PO format and XPLINK are applicable only for program objects. PO format is the version of the program object. XPLINK indicates whether any routines use XPLINK linkage conventions. Compat level designates the lowest OS release at which the release's binder could rebind this object. Note that the level at which the module can be executed is determined by the PO format.

D

Linking Program. The last line in the module summary identifies the linking program (VS linkage editor or binder) that created the module. For example:

*****PROGRAM OBJECT PROCESSED BY BINDER

This is applicable to a program object.

****LOAD MODULE PROCESSED EITHER BY VS LINKAGE EDITOR OR BINDER

The load module is either created by the linkage editor and processed by the binder, or created by the binder and processed by the linkage editor.

E

PMAR and PMARL. For program objects, the PMAR and PMARL are displayed in hexadecimal for diagnostic purposes, preceded by:

Table 1 summarizes the attributes of program objects and load modules. The first column shows the bit position. Columns 2 and 3 show the displayed constant and its meaning for the OFF condition. Columns 4 and 5 show the displayed constant and meaning for the ON condition.
