APAR status

• Closed as program error.

Error description

• Rational Developer for System z 9.5.1.2 LPEX Editing lines
  containing BIDI characters results in syntax "error token"
  messages.
  
  When editing COBOL members and editing a line containing BIDI
  characters some wrong syntax errors are displayed while no
  major change was performed on the source code.
  
  scenario :
  Open an element (COBOL type) for edit with LPEX editor ISPF mode
  edit a line containing BIDI charecters (as in pront screen) -
  deleting even a blank
  some wrong "error token" messages are displayed.
  
  Then also:
  - "Content Assist" option not shown
  - "Program Control Flow" option is disabled
  - "Mouse hover" assist does not function
  

Local fix

Problem summary

• In complex combinations of mixed Latin-Hebrew text, COBOL parser
   did not determine the end of the line correctly and as result
  took first character of next line as continuation of the current
   line.
  The wrong behavior occurred because BIDI mask injected to obtain
  correct visual rendering were removed from the line
  inconsistently to determined line length.
  

Problem conclusion

• The extra marks removal was dropped.  These BIDI marks are not
  illegal characters for COBOL parser, and changes in core parsing
   mechanism are more dangerous than dropping that removal.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for z Systems V9.5.1.6 Fix Pack which
  is available from the Recommended Fixes support download page:
