Last change: 2019 Dec 07 2 3 4 VIM REFERENCE MANUAL by Ralf Schandl 5 6 *zOS* *z/OS* *OS390* *os390* *MVS* 7This file contains the particulars for the z/OS UNIX version of Vim. 8 91.

Open source on z/OS UNIX |zOS-open-source| 15 16Contributors: ~ 17The port to z/OS UNIX was done by Ralf Schandl for the Redbook mentioned 18below. 19 20Changes, bug-reports, or both by: 21 22 David Moore 23 Anthony Giorgio 24 and others 25 26============================================================================== 271. ASCII/EBCDIC dependent scripts *OS390-has-ebcdic* *zOS-has-ebcdic* 28 29For the internal script language the feature "ebcdic" was added. With this 30you can fix ASCII dependent scripts like this: 31> 32 if has("ebcdic") 33 let space = 64 34 else 35 let space = 32 36 endif 37< 38 39============================================================================== 402. PuTTY and Colors *OS390-PuTTY* *zOS-PuTTY* 41 42If you see problems with syntax highlighting or screen corruptions when you 43connect to z/OS using Putty, try the following: 44 45- Configure Putty as "vt220" terminal (Connection->Data) 46- Add the following 3 lines to your vimrc: 47 48> 49 set t_AB=[4%p1%dm 50 set t_AF=[3%p1%dm 51 set t_CO=8 52< 53 54Note: is one character use <C-V><Esc> to enter it. 55 56============================================================================== 573. Motif Problems *OS390-Motif* *zOS-Motif* 58 59Note: Seen with Vim 6.*, never tested since. 60 61It seems that in porting the Motif library to z/OS, a translation from EBCDIC 62to ASCII for the accelerator characters of the pull-down menus was forgotten. 63Even after I tried to hand convert the menus, the accelerator keys continued 64to only work for the opening of menus (like <Alt-F> to open the file menu). 65They still do not work for the menu items themselves (like <Alt-F>O to open 66the file browser). 67 68There is no solution for this yet. 69 70============================================================================== 714. Bugs *OS390-bugs* *zOS-Bugs* 72 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. 76 77============================================================================== 785. Limitations *OS390-limitations* *zOS-limitations* 79 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. 85 86- The cscope interface (|cscope|) doesn't work for the version of cscope that 87 we use on our mainframe. We have a copy of version 15.0b12, and it causes 88 Vim to hang when using the "cscope add" command. I'm guessing that the 89 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 92 make any progress. 93 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. 96 97Disabled 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|) 103 104Never tested: 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 - TCL interface (|tcl|) 112 ... 113 114============================================================================== 1156.
