PH60992: DBD/PSB/ACB COMPARE MAY CAUSE ABEND0C4 DURING PROCESSING MEMBER WITH MULTIPLE PARAMETERS WITH LONG STRINGS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DBD/PSB/ACB Compare may cause ABEND0C4 when it processes a
  member which has multiple parameters such as REMARKS etc. with
  long strings. The utility obtains a report area storage using
  calculated number of row. When it processes the member which has
  multiple parameters with long strings, the calculated number is
  smaller than expected. As a result of this, the obtained storage
  is smaller than expected. The utility accesses to the unexpected
  storage area and it fails with ABEND0C4.

  ****************************************************************
  This APAR fixes the DBD/PSB/ACB Compare utility not to cause
  ABENDS0C4 when it generates the source-level compare reports
  and it processes a member which has differences for a lot of
  parameters of REMARKS or PATTERN parameter with long strings.
  
  This issue is caused by wrong calculation of a report area size
  for such member. The area size is calculated to a smaller value
  than actually needed and it causes shortage of report area
  buffer. As a result of this, the utility refers to the
  inaccessible storage area and it causes ABENDS0C4.
  
  This APAR corrects the calculation of the report area size.
