IC67013: PCOM: 3270 DISPLAY SESSION CRASH DOING PASTE FROM NOTEPAD

Personal Communications 5.9.7

APAR status

• Closed as program error.

Error description

• This customer use NFS DFS/SMB mounted disks to their endusers.
  On this network attached disks the enduser can find z/OS batch
  jobs (job control language JCL). When he tries to COPY / PASTE
  this JCL to a PCOM session with TSO in edit mode he get two
  symptoms.
  
  1. When they try to COPY / PASTE the very 1st time the data from
     a notepad to the PCOM TSO Member in edit mode, the PCOM
     session crashes.
  2. After a restart of PCOM the COPY / PASTE works, but just for
     the 1st line.
  
  They used the sample 'Kroner.test.txt' (see ECUREP). When you
  open this file with Notepad, it is shown in one single line
  as a long string. When you open the same file with Wordpad it
  looks OK.
  
  When you do the COPY / PASTE from the Wordpad all works fine.
  I looked to this file 'Kroner.test.txt' with a hex editor and it
  shows that there is a LF x'0A' control character which is
  interpreted by Wordpad as new line and in Notepad it is ignored.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users pasting data from Windows Notepad  *
  ****************************************************************
  * PROBLEM DESCRIPTION: While pasting data copied from certain  *
  *                      Windows Notepad files, the PCOMM        *
  *                      session crashes.                        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Some files have only line feeds at the end of lines instead of
  the regular carriage return line feed CR-LF combination. When
  the user tries to paste data copied from these files, PCOMM
  still processes it assuming that CR-LF is appended to the end
  of each line. As this scenario of only LF was not accounted for
  the paste fails and the PCOMM display session crashes.
  

Problem conclusion

• PCSEDIT.DLL has been changed to check for LF and notify the
  paste code to process accordingly, so the PCOMM display session
  does not crash when pasting.
  
  Fixed in Fix Pack PCOM 5.9.6.2
