Last change: 2019 Dec 07 + + + VIM REFERENCE MANUAL by Ralf Schandl + + *zOS* *z/OS* *OS390* *os390* *MVS* +This file contains the particulars for the z/OS UNIX version of Vim. + +1. ASCII/EBCDIC dependent scripts |zOS-has-ebcdic| +2. Putty and Colors |zOS-PuTTY| +3. Motif Problems |zOS-Motif| +4. Bugs |zOS-Bugs| +5. Limitations |zOS-limitations| +6. Open source on z/OS UNIX |zOS-open-source| + +Contributors: ~ +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'|) + - 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" + IBM Form Number: SG24-5944-01 + ISBN: 0738424633 + http://www-03.ibm.com/systems/resources/servers_eserver_zseries_zos_unix_redbook_sg245944.pdf + +Also look at: + http://www.redbooks.ibm.com + http://www-03.ibm.com/systems/z/os/zos/features/unix/ + http://www-03.ibm.com/systems/z/os/zos/features/unix/library/IBM+Redbooks/index.html + + + +------------------------------------------------------------------------------ + vim:tw=78:ts=8:noet:ft=help:norl: |
