How to User Name Remember Me? So i placed it here.
Beginners guide to Arexx
Move it if i’m wrong. Absolute beginners start here Because of some recent uploads to Aminet, i’d like to show users who are interested in learning how to create working ARexx scripts a shorter, faster and much more convinient way to interact with a tool like DirOpus4 While DO4-Version First a simple script that reads version information from selected files and present them as a list.
Last edited by BigFan; 04 July at As this is much too simple and still uses intermediate files which we have to remove from RamDisk to save memoryhere is a similar script to show each version string in a requester. This time we send our data to PIPE: This makes the script smaller and leaves no remains in RAM: This script can be enhanced, of course.
Like DOS command version, we could pass an argument like ‘full’ to get additional information. Try yourself before peeking the next script.
Arguments are taken with Arg name [name] The next is a small script to compare two folders. It does not require any selection, it will highlight files in both panes which have the same name. The script is not optimized for speed but yet is 2 to 8 times faster then DO4-Intersect The script can be altered to highlight mismatches instead.
When you start with ARexx the first time you’ll soon encounter the problem of finding errors. There are 2 more commands and they come very handy when debugging is not need all the time. TS – starts tracing TE – ends tracing While hunting bugs, it might be a good idea to use ‘say’ command for testing.
If you doubt a function to work as expected, put say infront. An output console or shell is required. Last edited by BigFan; 05 July at Never done anything in ARexx. Here is a short introduction: ARexx is a scripting language to send commands to a so called ‘host’. A host is an application with a message port, that listens to ARexx.
So what we do is simply sending a message containing our code.
The host has to interpet it and if possible process it. Whether the host answers back with valid return codes or not is up to host.
Full text of “Amiga Manual: ARexx User’s Reference Manual ()(Hawes, William S.)”
ARexx has 2 special vars to deal with return values. RexxMast can be found in Sys: To create an ARexx script any editor will do.
If you don’t have an editor at hand, you can still use AmigaDOS commands to create a script. An ARexx script starts with a comment. ARexx has aerxx variable typing, that means a var has not to be declared as Int, Float, String. You might use any single char as a variable. Last edited by BigFan; 14 July at Table of content added.
Now if you got too ardxx free time, then do it in AmigaDos: But using it helps to identify rexx scripts among others.
Thank you for taking the time to publish the useful tutorials. Find More Posts by amigakit. Thanks for the flowers Now after we did what the author raexx without asking why, it’s time to have a look at syntax! Though DOS batchfiles and Rexx scripts look similar there are fundamental differences.
Check out quotation marks. Where DOS expects double quotes “, Rexx uses single quotes ‘. DOS will not deal with path names as strings if they contain white spaces, until wrapped in “”. ARexx on the other hand uses ‘ single quotes. If you want to send a ” from within a rexx amigz, wrap it in single quotes which is very hard to read and srexx to errors.
The path contains white space. The error code is sent by DOS command cd. Cd can’t find “Ram”. The more you glue together, the more gibberish it looks like.

Right now you have learned a new ARexx command. Address Adress is used to switch between hosts, to send our messages to a new recipient. Address this is no commandbut builtin function. Last edited by BigFan; 06 July at Originally Posted by arfxx.

For example here you can find short but very cool AmigaDOS script to view version of the file in a standard system requester.
It even compares if there is different version loaded in ram compared to file on the filesystem. Here’s my version of the “Version number in DOpus requester” script. It was published as part of the DOpus4Plus packageso it’s a little more complex because like all scripts in the package it has German and English strings included.
I’m posting it, because it illustrates how to change button texts for the DOpus requester it’s changed to “Next” when viewing several files and changed back before the script exits. Last edited by Korodny; 05 July at Always good to have additional examples.
In my opinion the debugging is an issue while scripting with ARexx. Perhaps some more integrated environment needed there.

Enhanced version info This script can be enhanced, of course. Comparison of directories The next is a small script to compare two folders.

Piping might be used as well. Another big difference is the way we set comments.

Rewriting the code block again and again with lots of – if – then – select -when – constructs isn’t fun at all.
