PM39846: Data set in use error. COBOL or PL/I editor locks if invalid characters.

Rational Developer for System z 8.5

APAR status

• Closed as program error.

Error description

• Open a z/OS file using the COBOL or PL/I editor that contains
  invalid bytes. You'll get a warning that the file is opened in
  read-only mode.  That's expected.
  Now try to edit that file under TSO's ISPF editor.  'Dataset in
  use' error is seen. That's wrong. If the file is in read-only
  then another user should be able to edit it.
  This happens with the COBOL editor and the PL/I editor and RD/z
  8.0.1 and 8.0.2.
  

Local fix

Problem summary

• The BROWSE flag was not set to ON  in case of non-round trip
  characters found in the file.
  

Problem conclusion

• The code has been fixed by setting the BROWSE flag to ON in case
  of non-round trip characters found in the file and the file is
  opened in READ ONLY mode.
