Problem summary

• APAR NUMBER:  PJ40723
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  TAPE I/O AND ERROR RECOVERY
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  ZSTAT SYSHEAP NAME-ITAPE.* shows incorrect information.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/cp/cefe.cpy
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  None.
  
  Support Files:
  None.
  
  OTHER BINARIES TO BUILD: YES
  (C) <sys>/obj/cctape.o
  (C) <sys>/load/CPS0.so
  
  COMMENTS:
  When ZSTAT is used to display the system heap that has been
  obtained by TPF, the owner names that are displayed for the
  tape blocking buffers are incorrect. The correct format should
  be ITAPE.<tape name> but the information displayed contains
  unpredictable characters instead of the tape name. This is due
  to an incorrect stack area being used by routine CPMPINGB in
  copy member CEFE.cpy.
  

Problem conclusion

• SOLUTION:
  Routine CPMPINGB in copy member CEFE.CPY of CCTAPE.asm has been
  updated to correctly set the mid-level component of the owner
  name.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: NO
  None.
  
  BUILD COMMANDS AND INSTRUCTIONS: YES
  #maketpf commands for linux
  maketpf -f CPS0 cctape.o
