If CVAF detects an error, module ICVCME02 is called to produce
an ABEND18B dump for the following conditions. The following error
types relate to the error type that is identified on the title line
of the dump.
- For CVAF Error Type 1:
- The indexed VTOC is disabled.
- Message IEC606I RCxxx is issued to report
the error.
- For CVAF Error Type 2:
- The W/A identified on the title line of the dump is the calling
program's work area.
- Examine the work area pointed to by workarea in
the following example to locate the eye-catcher CVPL. It might
be necessary to scan backwards from the start of the W/A. The CVSTAT
field (CVPL + X'07') contains a 1-byte status code describing
the error. See CVSTAT field codes for a description
of these codes.
- For CVAF Error Type 3:
- The problem is an Abendnnn (except ABEND18B)
in either CVAF or in a function called by CVAF.
- The W/A identified on the title line of the dump is the work area
for the module identified in MODNAME on the title line.
- Starting at the work area pointed to by workarea in
the following example, examine the storage preceding the W/A (scan
backwards from the start of the W/A) to locate the eye-catcher CVPL.
The CVSTAT field (CVPL + X'07') contains a 1-byte status
code describing the error. See CVSTAT field codes for
a description of these codes.
The dump title line is in the following format. See
Figure 1 for a sample title line.
MODNAME JOBNAME CVAF ERROR TYPE n TCB=tcbaddr W/A=workarea
where:
- MODNAME is the CVAF module involved
- n is the error type (1, 2, or 3)
- tcbaddr is the TCB address
- workarea is the work area address

The CVFCTN field (CVPL +X'06') and the CVSTAT field (CVPL
+X'07') in the failure-related CVPL identify the failure-related
CVAF function and CVAF status, respectively. For a description of
function code values, see Table 1.
