PI53065: COB V5.2 COMPILER ASSIGNS "ADDRESS OF" TO VARIABLES IN SELECT & FETCH FOR DB2 PROGRAMS USING INTEGRATED COPROCESSOR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DB2 programs compiled with COB V5.2 that use the integrated DB2
  coprocessor and are tested with Debug Tool do not have the
  actual values of the DB2 variables displayed in Debug Tool for
  variables contained in a SELECT or FETCH.  Instead, Debug Tool
  shows an address for each variable contained in the SELECT or
  FETCH.
  
  Example of output:
  
  0004   ADDRESS OF DBLCOL-LENDING-TYPE-N OF DBLCOL-RECORD
  0005                            X'29A1BFA8'
  0006   ADDRESS OF DBLCOL-STOCK-BOND-TYPE-N OF DBLCOL-RECORD
  0007                            X'29A1BFB1'
  
  The compiler generates "ADDRESS OF" because the DB2 coprocessor
  is converting the EXEC SQL into a call that contains "ADDRESS
  OF", and the compiler is generating the DWARF automonitor info
  based on that instead of what's in the original source.

  ength_of_and_address_of_in_automonitor_output?lang=en
  discusses that when "ADDRESS OF" is used in the COBOL code that
  COB V5.1 will now display the address.  However, this should
  not be applicable to the variables in a SELECT and FETCH.

  ****************************************************************
  The compiler generated a debug auto monitoring information
  based on internally generated COBOL statements from the EXEC
  SQL statements, instead of the SQL statements themselves, which
  is why we got the address of a host variables instead of the
  host variable itself in the auto monitoring table.
