Roadie Arrex Usage

npagonis73 · 24 April 2021, 12:41

Hi guys

Can someone give me an example how can I use arrex commands in a program that supports it. For example how can I use the arrex commands in Roadie or another program that supports arrex. Please could someone give me an example of how the command should look like and potential use of it.

Thanks

AREXX exists as an interprocess communication scripting language. Trying to use AREXX ports without knowing the language is kind of tricky. At least knowing the correct spelling of it will help find more information. Also, the language is the Amiga version of the REXX language used by OS/2 Warp so that might give you a few search terms to look into.

Ok thanks for the info. Will try to look into it.

If you don't own the Amiga OS 3.1 ARexx book then find it online for the start. There are more books available of course. There is also ARexxGuide2: http://aminet.net/search?query=arexxguide2

About Roadie. The documentation and ARexx features are limited:

Code:

ARexx Commands (Default port is ROADIE)
- ONLINE                        [ Go Online ]
- OFFLINE                       [ Go Offline ]
- SHOW                          [ Show the main Roadie interface ]

As you can see there are only three commands. Important info is that Roadie port is called "ROADIE". Interprocess communication is usually done by message ports. If you want to talk to Roadie you have to switch to its port. E.g.: "ADDRESS ROADIE".

Thanks a lot daxb. That is why I chose roadie as an example. Because it is simply 3 commands. So what would the command or script look like if I wanted to talk to roadie and let's say show it's gui which is the third arexx command? What is the advantage of using arexx (if there is any) and not the normal dos commands of the program?

npagonis73 · 24 April 2021, 17:07

Guys sorry for all those questions but I am just trying to understand arexx usability over dos commands.

daxb · 24 April 2021, 18:31

The simplest form:

Code:

/**/
ADDRESS ROADIE
SHOW

ARexx is an interpreted high level scripting language. Amiga DOS has very limited scripting possibilities. So, if you want to do some more advanced programming you would choose ARexx. However, with Amiga DOS you cannot talk to other programs like it is possible with ARexx message ports.

The Roadie example doesn't show the advantage of ARexx over DOS.

A long answer would be much longer.

If you are interested in ARexx you can also check stuff on Aminet or WWW. Or check your installed programs manuals for ARexx interface. This should give you an idea.

Great, thank you very much for your time and explanation. I get the difference and I will search for more info online as you suggested.

The Amiga OS online manuals include ARexx in a Wiki format that makes for a decent reference: https://wiki.amigaos.net/wiki/AmigaOS_Manual:_ARexx

If you're using OS 3.5+ (including OS 3.1.4), Workbench itself also includes an ARexx port. Use of that was included in the OS 3.9 ARexx manual, but someone has decided to remove it from the OS manual posted above. Instead, it has been awkwardly added to the basic use of Workbench page here: https://wiki.amigaos.net/wiki/AmigaO...Rexx_Interface

Do you know if there exists an Amiga Guide version of this? For offline reading or quick access it would be better then HTML or TEXT. Years ago I used the text version from NDK3.9 but that was very time consuming searching the needed information.

You can find other various books/readings about ARexx here as well : https://archive.org/search.php?query=arexx

Thank you all guys for your help. I am digging into arrex stuff slowly but steadily using all your sources and guides.

Take care

Not that I know of. OS 3.9 came with a HTML version too for offline use, but it's a bit clunky to load a browser each time. An AmigaGuide conversion would be nice alright...

@Deadalus:
I have no experiences with convert to guide tools but there are some on Amient: http://aminet.net/search?query=convert+to+guide
I would try it myself but my Amiga is without network for some years now. Just for the case someone is interested.
