Diagnostic cross-reference and assembler summary
This section of the listing summarizes the error diagnostic messages issued during the assembly, and provides statistics about the assembly.
The sample listing shown in Figure 1 contains a combination of z/OS® and CMS data sets to show examples of the differences in data set information.

- 1
- The statement number of a statement that causes an error message,
or contains an MNOTE instruction, appears in this list. Flagged statements
are shown in either of two formats. When assembler option FLAG(NORECORD)
is specified, only the statement number is shown. When assembler option
FLAG(RECORD) is specified, the format is: statement(dsnum:member,record),
where:
- statement
- is the statement number as shown in the source and object section of the listing.
- dsnum
- is the value applied to the source or library data set, showing
the type of input file and the concatenation number.
P
indicates the statement was read from the primary input source, andL
indicates the statement was read from a library. This value is cross-referenced to the input data sets listed under the sub-headingDatasets Allocated for this Assembly
5 . - member
- is the name of the macro from which the statement was read. On z/OS, this can also be the name of a partitioned data set member that is included in the primary input (SYSIN) concatenation.
- record
- is the relative record number from the start of the data set or member which contains the flagged statement.
- 2
- The number of statements flagged, and the highest non-zero severity
code of all messages issued. The highest severity code is equal to
the assembler return code. If no statements are flagged, the following statement is printed:
No Statements Flagged in this Assembly
If the assembly completes with a non-zero return code, and there are no flagged statements, it indicates there is a diagnostic message in the Option Summary section of the listing (see Figure 1).
For a complete discussion of how error messages and MNOTEs are handled, see Assembly error diagnostics.
- 3
- The current release of High Level Assembler and the last PTF applied.
- 4
- Provides information about the system on which the assembly was
run. This information is:
- The name and level of the operating system used to run the assembly.
- The job name for the assembly job. If the job name is not available,
(NOJOB)
is printed. - The step name for the assembly job. If the step name is not available,
(NOSTEP)
is printed. - The procedure name for the assembly job. If the procedure name
is not available,
(NOPROC)
is printed.
- 5
- On z/OS and CMS, all data
sets used in the assembly are listed by their standard ddname. The
data set information includes the data set name, and the serial number
of the volume containing the data set. On z/OS, the data set information can also include
the name of a member of a partitioned data set (PDS) or library (PDSE).
If a user exit provides the data set information, then the data set name is the value extracted from the Exit-Specific Information block described in Exit-Specific Information block.
The
Con
column shows the concatenation value assigned for each input data set. You use this value to cross-reference flagged statements, and macros and copy code members listed in the Macro and Copy Code Cross Reference section.z/OS: On z/OS, the data set name for all data sets is extracted from the z/OS job file control block (JFCB). If the data set is a JES2 spool file, for example, the data set name is the name allocated by JES2. If the data set is allocated to DUMMY, or NULLFILE, the data set name is shown as NULLFILE.
CMS: On CMS, the data set name is assigned one of the values shown in Table 1.
File Allocated To: | Data Set Name |
---|---|
CMS file | The 8-character file name, the 8-character file
type, and the 2-character file mode of the file, each separated by
a space. If the data set is a disk file in the Shared File system,
the volume serial number contains “** SFS ”. |
Dummy file (no physical I/O) | DUMMY |
Printer | PRINTER |
Punch | PUNCH |
Reader | READER |
Labeled tape file | The data set name of the tape file |
Unlabeled tape file | TAPn ,
where n is a value from 0 to 9, or from
A to F. |
Terminal | TERMINAL |
- z/VSE®:
- On z/VSE, the data set name is assigned one of the values shown in Table 2.
File Allocated To: | Data Set Name |
---|---|
Disk | The file-id |
Job stream (SYSIPT) | None |
Library (Disk). The ddname is shown as *LIB* . |
The file-id |
Printer | None |
Punch | None |
Labeled tape file | The file ID of the tape file |
Unlabeled tape file | None |
Terminal (TERM) | None |

- Output data sets do not have a concatenation value.
- 10
- The minimum storage required for an in-storage assembly.
- 11
- The number of primary input records read by the assembler. This count does not include any records read or discarded by the SOURCE user exit.
- 12
- The number of records read from the ASMAOPT file (z/OS and CMS) or the Librarian member (z/VSE) by the assembler.
- 13
- The number of records read from the libraries allocated to SYSLIB on z/OS and CMS, or assigned to the Librarian on z/VSE. This count does not include any records read or discarded by the LIBRARY user exit.
- 14
- The count of the actual number of records generated by the assembler.
If you have used the SPACE n assembler instruction,
the count might be less than the total number of printed and blank
lines appearing in the listing. For a SPACE n that
does not cause an eject, the assembler inserts n blank
lines in the listing by generating n/3 triple-spaced
blank records, rounded to the next lower integer if a fraction results.
For a SPACE 2, no blank records are generated. The assembler does
not generate a blank record to force a page eject.
This count does not include any listing records generated or discarded by the LISTING user exit.
- 15
- The number of object records written. This count does not include any object records generated or discarded by the OBJECT or PUNCH user exits.
- 16
- The number of ADATA records written to the associated data file.
- 17
- On z/VSE, the assembly
start and stop times in hours, minutes, and seconds.
On z/OS and CMS, the assembly start and stop times in hours, minutes, and seconds and the approximate amount of processor time used for the assembly, in hours, minutes, and seconds to four decimal places.
The assembly start time does not include the time used during assembly initialization, which allocates main storage and data sets and processes the assembler invocation parameters. The assembly stop time does not include the time used during assembly termination, which deallocates main storage and data sets.
