PH18124: S0C4 ON SET ADDRESS STATEMENT WHEN RUNNING IN AMODE(64)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Testing 64-bit mode, COBOL program receives a s0c4 at execution
  time on a SET ADDRESS statement.
  

Local fix

• Compile and execute in 31-bit mode
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.3 compiling and *
  *                 running programs that set the addresses of   *
  *                 the CVT-BLOCK and SMF-BLOCK to pointers in   *
  *                 AMODE64 (LP(64) compiler option was          *
  *                 specified during the compile).               *
  ****************************************************************
  * PROBLEM DESCRIPTION: ABEND: Compiler fails with an S0C4      *
  *                      error at runtime on SET ADDRESS         *
  *                      statement when attempting to set        *
  *                      CVT-BLOCK and SMF-BLOCK to pointers.    *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF and recompile with    *
  *                 affected pointers changed to pointer-32      *
  ****************************************************************
  Addresses of CVT-BLOCK AND SMF-BLOCK are fixed as 4-byte
  addresses by System Z architecture. Setting 8-byte pointers to
  these addresses fills the high word of the pointer with random
  values which results in the S0C4 ABEND.
  

Problem conclusion

• The compiler was changed so that Pointer-32 data-items are used
  correctly to allow for proper set address statement behavior.
  

Temporary fix
