#VMCE #rexx EE goes XEDIT - compiling a wish list

#VMCE #rexx

Martin Scheffler All Messages By This Member #4341 I am using XEDIT and its clones since VM/SP Release 1 up to today ... and counting. EE is great work by Dr. Hans-Walter Latz, but I miss a lot of features that XEDIT and KEDIT have. I have done massive extensions to EE to make it more XEDIT-compatible. A common infrastructure already exists for the SET / QUERY / EXTRACT / MODIFY / TRANSFER subcommands. Actually I am researching how EE could integrate with bREXX. Having a macro capability powered by REXX is my first wish. The ingredients for the ALL macro will follow (SET SELECT, SET DISPLAY ...). Do you think it is desirable and feasable to have a decent subset of XEDIT as part of VM/370 CE ?

Bertram Moshier All Messages By This Member #4530 Hello, I would love to see XEDIT on VM/CE.? I know you have a lot invested in EE, but have you thought about looking at the product KEDIT?? While written for Windows 32 bit and most likely in C or C++, I'm wondering if it might help you with the logic?? Maybe not. Yes, I would love to have XEdit functionality in VM/CE.

Dave Wade All Messages By This Member #4532 开云体育 Of course its desirable to have as much of XEDIT as possible under VM/370 CE, except of course it limits the memory available.

There is a German idiom "Eulen nach Athen tragen (, see also )": KEDIT is my principal editor since 1988. I have even written a UTF-8 import/export filter for it to deal with source code containing French and German literals and comments. I'd like to see KEDIT GPLed and opensourced on GitHub when (if?)

[email protected] All Messages By This Member #4535 开云体育 I think it goes without saying that we would very much like to see Rexx compatibility for EE and a more XEDIT-like working - although it is not at all bad at the moment, just a bit different. Because we are all very busy, it would be good if there would be an easy way to be involved in testing, e.g. by having a way to up/downgrade your EE installation, for example a github repo where we can easily download versions. I would like to tell you what my personal priorities would be. As I am a late VM user (I had the course in 1987 on (probably) VM/SP R5 and had already my first opportunity to use XEDIT in 2019) (because in 1987 I only ever used VM to IPL MVS in it and then PR/SM came along) - all my Rexx editor macros start with ADDRESS ISREDIT. Also, as opposed to most people I work with, I use the 3270 emulator keyboard as was intended, with enter mapped to linefeed and ctrl-right to send. So I am using XLIST and I wish it behaved a bit more like FILELIST (we could probably do that in Rexx now), I have X synonymed to EE and I find it almost workable. But I would very, very much have it behave a bit more like modern XEDIT. best regards, René Jansen. toggle quoted message Show quoted text On 27 Oct 2022, at 03:34, Martin Scheffler <San-Lorenzo@...> wrote: No feedback ... are editors much less significant in the (emulated) mainframe community now since most people are doing it the Zowe way ?

There are obstacle in implementing this, including getting EE out of the user area at X'20000' so that more than a small subset of CMS commands can be issued while EE is running.

Fully agreed. I need to acquire more knowledge to enter this area. In the 1990s I was a very experienced professional assembler programmer on the Motorola M680x0 family. Used on bare metal including basic setup of the MMU, as a VERSAdos system service or as an interface library for Pascal programmers. I have to learn all this for System/370. Please tell me where begin to read if there is a faster path than starting at GA22-7000-6? IBM System/370 Principles of Operation . What do I need for "EE goes XEDIT" ? from C call an assembler routine to establish a CMS SUBCOM evironment "XEDIT" an assembler routine which receives subcommand calls and calls the C part of the editor an assembler routine using EXECCOMM to share REXX variables, EXTRACT needs this

[email protected] All Messages By This Member #4544 开云体育 Nothing really modern in the usual sense but I think about the ability to make fullscreen apps with it - don’t know how modern that exactly is, and driven by the fact that getting IOS3270 to work and integrate with the Rexx variable pool without the source would be hard . I probably meant things looking and feeling the same as VM/ESA or z/VM. Where the FILEL command probably already could be done in Rexx. I would also like what Bob points out, which is compatibility with Rexx XEDIT macros and ADDRESS but I understood that is a little bit further away. Another thing I would like very much: an SI line command which opens a new line on every enter - in the sense of what probably can be added now. 搁别苍é. toggle quoted message Show quoted text On 27 Oct 2022, at 11:45, Martin Scheffler <San-Lorenzo@...> wrote: I have to learn all this for System/370.

Bob Bolch All Messages By This Member #4548 Not to go too far off topic, but you can write REXX full screen applications on VMCE 1.1.2 with calls to the old SAS Rexx Function Package. The new HELP EXEC is written in REXX.

Bob Bolch All Messages By This Member #4550 Hi Martin, I started working on VM/370 over 3 years ago to update a platform independent REXX implementation into one with the capabilities present in early VM/SP .?? I had to write the CMS system support code for features not available in VM/370, but neccesary to support REXX macros for edit subcommands. 1. SUBCOM support 2. CMS Nucleus Extension support (NUCEXT) 3. Rexx function package support 4. EXECCOMM support to extract or set REXX variable values from external programs ( like EXECIO). 5. EXECIO. Next, I am trying to figure out if the EE implementation has (or can be made to have) the execution characteristics necessary to implement REXX macro support.?? Figuring out the steps to support writing editor commands in REXX is hard, and I have been using CMS for almost 50 years. You have stated the 50000 foot view, but the devil is in the details.

Martin I think SP3 compatibility would be a good start. BREXX still has a problem with parsing its command line, so that will be a challenge, in and of itself. Would support of EXEC2 be present, until BREXX is fixed? I don't know where XEDIT lives in memory, when invoked. Does putting it, or part of it in a DisContiguous Saved Segment (DCSS) hurt or help? Was it in the CMS DCSS since SP 1? ?... Mark S.
