CVAF dumps

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. For a description of the CVSTAT codes, see CVSTAT field codes .
