Re: VM/370 CE - Editing an APL function
¿ªÔÆÌåÓýThank you! It seems that it *seems* to work, but it does not work completely. I cannot divide or multiply at the moment. As I am trying to put a Docker container together that handles all the languages in??(apl, snobol, simula, forth etc) on Hercules, I would like to find out where this comes from.I tried to locate J¨¹rgen Winkelmann's MVT for APL but had a hard time, eventually downloading the files from the wayback machine where I put the link in that is mentioned on the museum website, and that is only ten years old. I have it now but it also has a lot of moving parts, so I would prefer to fix just this problem. If anyone has an approach or suggestion, I would love to hear them. best regards, ¸é±ð²Ô¨¦.

Re: VM/370 CE - Editing an APL function
CHARACTER ERROR --> you are not using the "right" key
DOMAIN ERROR --> is the "right" thing and is what I get with MVT DECIMAL EXCEPTION --> is "wrong" and is what I get with APL\360 under VM/370 CE (see photo) div by zero Marco |

I am able to revise lines into something harmless, but deleting lines does not seem to stick.
I did now: ? ? ? 1 0 CHARACTER ERROR ? ? ? ? ? ? 1 when compared to gnu apl, it is not that different: ? ? ? 1¡Â0 DOMAIN ERROR ? ? ? 1¡Â0 ? ? ? ^^ best, ¸é±ð²Ô¨¦

Re: VM/370 CE - Editing an APL function
¿ªÔÆÌåÓýoh dear, curse this modern technology! and just let me append something to a forum again ... (we'll have to get this bitnet thing connected again)Of course, the web interface shows me *my* paste and they know about eachothers formats. When looked at from a different browser, which I suspectingly did, there was no picture. Not being known for easily giving up, I put it here for your admiration if interested:? I'll send some APL in text in a next message (but enough work for today already) to see how that comes out over different media. best regards, ¸é±ð²Ô¨¦.

Re: VM/370 CE - Editing an APL function
¿ªÔÆÌåÓýTwo things warrant me replying to myself:1) The mail interface did not accept the attachment, but the web interface for this group did; you can look at the screenshot at?/g/h390-vm/message/5674?to see the glory of the 3270 font with the (for me) correct color and a working APL\360 system to boot; 2) Pasting from my notes from several years ago introduced an error in the dyalog keyboard url; it should be??. best, ¸é±ð²Ô¨¦.

Re: VM/370 CE - Editing an APL function
Let me quickly document my setup on macOS and ARM64. I can assure you that the end product works. My main working machines are a macbook pro m2 and a mac mini m1 with a good screen for home use. The mini has a Unicomp APL Model M usb keyboard. Both machines run Sonoma 14.4.1
?
I have built Hercules with hercules-helper () some time ago; but this week I installed it on a colleague's mac at work with just 'brew install hercules' because we did not have a lot of time. This also works although you might not get the most current version.
?
For 3270 emulators I mostly use ZOC and c3270. The latter for APL, because I could not yet get ZOC to work with APL. Because of muscle memory, I need the [Send] (ENter) key mapped to the right CTRL on the Model M (PC) keyboard and the right command key on the laptop. The enter/return key needs to be newline. This is done with a combination of remapping the keyboard and modifying the emulators. The keyboards are remapped with Karabine 14.13.0 (), using grave_accent_and_tilde and non_us-backslash. My [send] and [clear] keys are reversed on the laptop because on the Model M send needs to be right-ctrl but on the laptop it needs to be right-command because that is a bigger key. If you are one of those youthful people that don't need to remap because you are using [enter] for [send], you can skip this step.
?
We now need to make the keyboard produce APL glyphs.?Reading the Dyalog website I found the missing link: the keyboard, when used on a Mac, needs a special set of keyboard layout icon files (downloadable from https:) that needs to be added to Library/Keyboard Layouts - then, in the settings dialog, these can be chosen as a locale. When this is active, the keyboard can be used with full APL functionality in all applications, with all Unicode fonts that contain APL characters. IBM Plex Mono, for example, has excellent support. The APL characters are then accessible in combination with the option key, and from the Unicom APL keyboard in combination with the left Windows key. This is a useful step because it also enables gnu-apl and others.
?
The rest will focus on c3270 and not on ZOC. I use c3270 because this also works over ssh and other non-graphical connections in local sessions over tmux. When connection to remote machines I always do that in tmux sessions because when something happens to the connection, you can always tmux attach into your running sessions when the connection is back up. For MVS consoles this is important and for VM very useful, although VM's session recoverability always was a lot better. c3270 has more faithful font reproduction than x3270, the latter struggled with high resolution screens for a long time.?
?
For c3270 you can have startup parameters in a file called ~/.c3270pro
Its contents on my machine is
?
! .c3270 settings file for macOS and IBM Model m (USB,PS/2) keyboards, iTerm2
! and also usable on MacBook Pro keyboard
! this file needs to go in the user's home directory
?
! Make sure the reported terminal in iTerm2 is set to xterm
! character encoding is Unicode(UTF-8)
! Use Karabiner-Elements to map
! ? ?right_alt ? ? -> keypad_hyphen
! ? ?right_control -> grave_accent_and_tilde
?
?
! we want the 3270 enter and newline configuration like it was intended
c3270.keymap.3270: \
<Key>U+007F: Erase\n\
<Key>Return: NewLine \n\
<Key>BackSpace: BackSpace \n\
<Key>`: Enter() \n\
<Key>END: EraseEOF() \n\
<Key>¡ì: Clear()
?
! Note: mac keyboard:
! Erase EOF is fn-cursor_right
?
! assign the 3270 standard scroll functions to kb PageUp and PageDown
c3270.keymap.scroll: \
<Key>PPAGE: PF(7)\n\
<Key>NPAGE: PF(8)
?
! use the keymaps defined above
c3270.keymap: 3270,scroll
?
I use a lot of terminal apps on the mac - kitty and iTerm2 are used for normal work - but for 3270 work I run Alacritty () with Richard Banffy's 3270 ()?font. This is a great working font for mainframe work that reminds me of yesteryears; I am not sure it contains APL glyphs but the macOS substitution mechanism will care of that if not - I did not go into that fully yet.
?
We then start c3270
?
c3270 localhost:3270 -model 3279-5
?
When your hercules runs on localhost, that is, otherwise any dns name or ip address will go into that place.?
?
Logging on to VM/370CE, issue the
?
TERM APL ON
?
and switch the mac keyboard to the dyalog defined one. Now on an APL keyboard you have the symbols available, but on the laptop you do not, but you can go to the keyboard menu, and choose "Show keyboard viewer" ; you can float this over other windows. Pressing the option key (the left one, that was not remapped) displays the actual keys of the APL symbols.
?
Program entry and editing works as Mike Beer indicated. Not sure if this list accepts attachments, but this screen shot shows editing a program on 3270 using APL\360.
?
?
Where the program 'program' first displays a range from 1 to 99 but then is edited to assign 'foo bar baz' to a and then display it.
?
So don't give up, it all works great and it is a very rewarding experience.
?
best regards,
?
