Problem summary

• APAR NUMBER:  PJ40677
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  TPFCS ZBROW ROUTINES
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  ZBROW COL DUMP and ZBROW ELEMENT DISP may fail with CTL-3 in
  CISO or include garbage in display.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/rt/cj10.c
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  (C) base/obj/cj10.o
  (C) base/load/CJ10.so
  
  Support Files:
  base/lst/cj10.lst
  base/lst/CJ10.map
  
  OTHER BINARIES TO BUILD: NO
  None.
  
  COMMENTS:
  When ZBROW COLLECTION DUMP and ZBROW ELEMENT DISPLAY commands
  are issued, unpredictable results may occur if the collection
  contains hexadecimal contents which translate to C control
  characters, for example %n, %d, %c. The problem occurs when
  attempting to display these characters. This is because
  vfprintf attempts to process the character display as control
  characters. A CTL-3 may occur out of CISO function vfprintf. If
  the CTL-3 does not occur, the contents of the collection will
  not display correctly.
  

Problem conclusion

• SOLUTION:
  Program cj10.c has been changed to pass %% in the output string
  when trying to print or write a percent sign as part of the
  collection contents to the console or file.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: NO
  None.
  
  BUILD COMMANDS AND INSTRUCTIONS: YES
