20 Changes, bug-reports, or both by:
26 ==============================================================================
27 1. ASCII/EBCDIC dependent scripts *OS390-has-ebcdic* *zOS-has-ebcdic*
29 For the internal script language the feature "ebcdic" was added. With this
30 you can fix ASCII dependent scripts like this:
39 ==============================================================================
40 2. PuTTY and Colors *OS390-PuTTY* *zOS-PuTTY*
42 If you see problems with syntax highlighting or screen corruptions when you
43 connect to z/OS using Putty, try the following:
45 - Configure Putty as "vt220" terminal (Connection->Data)
46 - Add the following 3 lines to your vimrc:
54 Note:
\e is one character use <C-V><Esc> to enter it.
56 ==============================================================================
57 3. Motif Problems *OS390-Motif* *zOS-Motif*
59 Note: Seen with Vim 6.*, never tested since.
61 It seems that in porting the Motif library to z/OS, a translation from EBCDIC
62 to ASCII for the accelerator characters of the pull-down menus was forgotten.
63 Even after I tried to hand convert the menus, the accelerator keys continued
64 to only work for the opening of menus (like <Alt-F> to open the file menu).
65 They still do not work for the menu items themselves (like <Alt-F>O to open
68 There is no solution for this yet.
70 ==============================================================================
71 4. Bugs *OS390-bugs* *zOS-Bugs*
73 - Vim will consistently hang when a large amount of text is selected in
74 visual block mode. This may be due to a memory corruption issue. Note that
75 this occurs in both the terminal and gui versions.
77 ==============================================================================
78 5. Limitations *OS390-limitations* *zOS-limitations*
80 - No binary search in tag files.
81 The program /bin/sort sorts by ASCII value by default. This program is
82 normally used by ctags to sort the tags. There might be a version of
83 ctags out there, that does it right, but we can't be sure. So this seems to
84 be a permanent restriction.
86 - The cscope interface (|cscope|) doesn't work for the version of cscope
87 that we use on our mainframe. We have a copy of version 15.0b12, and it
88 causes Vim to hang when using the "cscope add" command. I'm guessing that
89 the binary format of the cscope database isn't quite what Vim is expecting.
90 I've tried to port the current version of cscope (15.3) to z/OS, without
91 much success. If anyone is interested in trying, drop me a line if you
94 - No glib/gtk support. I have not been able to successfully compile glib on
95 z/OS UNIX. This means you'll have to live without the pretty gtk toolbar.
97 Disabled at compile time:
98 - Multibyte support (|multibyte|)
99 - Right-to-left mode (|rileft|)
100 - Farsi key map (|Farsi|)
101 - Arabic language support (|Arabic|)
102 - Spell checking (|spell|)
105 - Perl interface (|perl|)
106 - Hangul input (|hangul|)
107 - Encryption support (|encryption|)
108 - Langmap (|'langmap'|)
109 - Python support (|Python|)
110 - Right-to-left mode (|'rightleft'|)
111 - SNiFF+ interface (|sniff|)
112 - TCL interface (|tcl|)
115 ==============================================================================
116 6. Open source on z/OS UNIX *OS390-open-source* *zOS-open-source*
