PI72931: IBM EXPLORER FOR Z/OS (ZEXPL) USING THE SPLIT Editor Toggle TWICE IN A FILE OPENED IN READ ONLY MODE WILL OPEN IT IN EDIT MODE

APAR status

• Closed as program error.

Error description

• IBM Explorer for z/OS - zExpl
  
  When you use the COBOL editor to open a file that is controlled
  by a change management tool such as Endevor in read only mode
  and you use the split mode twice, the second instance of the
  split mode may open the file in edit mode even though the file
  is read only.
  
  Steps to reproduce:
  
  From the CARMA view select a COBOL program when prompted open
  it in Read Only mode.
  Select Window > Editor > Toggle Split Editor
  File is still open in browse only, and typing is NOT allowed
  Close split window
  Select Window > Editor > Toggle Split Editor  again
  Now you are able to type
  

Local fix

• Be sure that users cannot make a change to the file by
  protecting the file in RACF or some similar system security
  

Problem summary

• When a COBOL editor that was in read-only mode is split and then
  the split is closed and then split again, the read-only
  property gets lost and the editor wrongly becomes editable.
  

Problem conclusion

• When an editor is closed, certain session properties get cleared
  including properties that indicate whether the editor is in
  read-only mode.  When an editor is closed, including one that is
  the result of a split, the session properties indicating to use
  read-only mode are cleared and reset to edit mode.
  
  This APAR will be available in IBM Explorer for z/OS 3.0.1.5
