PI72689: S0C1 WITH MIX OF ASSEMBLER AND COBOL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an assembler program does a load and balr to a COBOL V6
  (or V5) program multiple times, an exception occurs after the
  second instance upon return to the assembler's caller.  The dsa
  of the assembler's caller is being reused and overlaid.  This
  only occurs when using LE run-time option RTEREUS .
  

Local fix

• Do not use RTEREUS.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Enterprise COBOL users running both COBOL    *
  *                 V5+ and pre-V5 programs in a reusable        *
  *                 runtime environment, enabled with the LE     *
  *                 runtime option RTEREUS.                      *

  * PROBLEM DESCRIPTION: Runtime ABEND ABEND0C1: when an         *
  *                      Enterprise COBOL pre-V5 program is      *
  *                      first run in a reusable runtime         *
  *                      environment established using the       *

  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  *                                                              *
  ****************************************************************
  When RTEREUS is active, the COBOL runtime must keep track of
  the state of the LE environment to keep it active but dormant
  when the main COBOL program returns control to the caller. The
  state information got out of sync when an V5+ program is
  introduced to the running environment, causing an overlay to
  the stack storage used by the main program.
  

Problem conclusion

• The COBOL runtime has been corrected to work properly for this
  scenario.
