PH01252: COBOL V6.1: U4088 IN Z/OS DEBUG TOOL DUE TO INCORRECT .DEBUG_SRCATTR DATA IN DWARF

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When source contains either CICS or DB2 statements, the
  z/OS Debug Tool would not start and a STO abend occurs
  (U4088/0C7).
  
  The debugger development team was able to identify the problem
  with the NUMBER compiler option causing more .debug_srcattr
  entries than the number of expanded source lines as well as
  incorrect mapping between the line number and alt_lineno.
  

Local fix

• Compile with NONUMBER
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL for z/OS V6.1 who  *
  *                 compile programs with TEST and NUMBER and    *
  *                 either CICS or SQL compiler options          *
  *                 programs that contain either CICS or DB2     *
  *                 statements and then try to debug these       *
  *                 programs using IBM z/OS Debug Tool.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: The z/OS Debug Tool would not start     *
  *                      and a STO abend occurs (U4088/0C7).     *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler was putting incorrect line numbers in the
  debugging information due to counting statements generated for
  CICS or SQL as regular COBOL statements.
  

Problem conclusion

• The compiler was changed to only count COBOL statements that
  show in the debug view for purposes of numbering the lines in
  debug information.
  

Temporary fix
