The port to z/OS UNIX was done by Ralf Schandl for the Redbook mentioned
|
||
below.
|
||
|
||
Changes, bug-reports, or both by:
|
||
|
||
David Moore
|
||
Anthony Giorgio
|
||
and others
|
||
|
||
==============================================================================
|
||
1. ASCII/EBCDIC dependent scripts *OS390-has-ebcdic* *zOS-has-ebcdic*
|
||
|
||
For the internal script language the feature "ebcdic" was added. With this
|
||
you can fix ASCII dependent scripts like this:
|
||
>
|
||
if has("ebcdic")
|
||
let space = 64
|
||
else
|
||
let space = 32
|
||
endif
|
||
<
|
||
|
||
==============================================================================
|
||
2. PuTTY and Colors *OS390-PuTTY* *zOS-PuTTY*
|
||
|
||
If you see problems with syntax highlighting or screen corruptions when you
|
||
connect to z/OS using Putty, try the following:
|
||
|
||
- Configure Putty as "vt220" terminal (Connection->Data)
|
||
- Add the following 3 lines to your vimrc:
|
||
|
||
>
|
||
set t_AB=[4%p1%dm
|
||
set t_AF=[3%p1%dm
|
||
set t_CO=8
|
||
<
|
||
|
||
Note: is one character use <C-V><Esc> to enter it.
|
||
|
||
==============================================================================
|
||
3. Motif Problems *OS390-Motif* *zOS-Motif*
|
||
|
||
Note: Seen with Vim 6.*, never tested since.
|
||
|
||
It seems that in porting the Motif library to z/OS, a translation from EBCDIC
|
||
to ASCII for the accelerator characters of the pull-down menus was forgotten.
|
||
Even after I tried to hand convert the menus, the accelerator keys continued
|
||
to only work for the opening of menus (like <Alt-F> to open the file menu).
|
||
They still do not work for the menu items themselves (like <Alt-F>O to open
|
||
the file browser).
|
||
|
||
There is 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'|)
|
||
- SNiFF+ interface (|sniff|)
|
||
- TCL interface (|tcl|)
|
||
...
|
||
|
||
==============================================================================
|
||
6. Open source on z/OS UNIX *OS390-open-source* *zOS-open-source*
|
||
|
||
If you are interested in other Open Source Software on z/OS UNIX, have a
|
||
look at the following Redbook:
|
||
|
||
Mike MacIsaac et al
|
||
"Open Source Software for z/OS and OS/390 UNIX"
|
||
