s no solution for this yet.

4. Bugs					*OS390-bugs* *zOS-Bugs*

- Vim will consistently hang when a large amount of text is selected in
  visual block mode.  This may be due to a memory corruption issue.  Note that
  this occurs in both the terminal and gui versions.

==============================================================================
5. Limitations     			*OS390-limitations* *zOS-limitations*

- No binary search in tag files.
  The program /bin/sort sorts by ASCII value by default.  This program is
  normally used by ctags to sort the tags.  There might be a version of
  ctags out there, that does it right, but we can't be sure.  So this seems to
  be a permanent restriction.

- The cscope interface (|cscope|) doesn't work for the version of cscope that
  we use on our mainframe.  We have a copy of version 15.0b12, and it causes
  Vim to hang when using the "cscope add" command.  I'm guessing that the
  binary format of the cscope database isn't quite what Vim is expecting.
  I've tried to port the current version of cscope (15.3) to z/OS, without
  much success.  If anyone is interested in trying, drop me a line if you
  make any progress.

- No glib/gtk support.  I have not been able to successfully compile glib on
  z/OS UNIX.  This means you'll have to live without the pretty gtk toolbar.
 
Disabled at compile time:
    - Multibyte support         (|multibyte|)
    - Right-to-left mode        (|rileft|)
    - Farsi key map             (|Farsi|)
    - Arabic language support   (|Arabic|)
    - Spell checking            (|spell|)

Never tested:
    - Perl interface		(|perl|)
    - Hangul input		(|hangul|)
    - Encryption support	(|encryption|)
    - Langmap			(|'langmap'|)
    - Python support		(|Python|)
    - Right-to-left mode	(|'rightleft'|)
    - TCL interface		(|tcl|)
    ...

6. Open source on z/OS UNIX		*OS390-open-source* *zOS-open-source*
