It will take some extra work, but SketchBlock could always process the paths to make them absolute before sending them to arexx.class. There are two possible options:
- Check if the path is relative or absolute; if it is relative, then add SketchBlock's absolute path
- If the path in the prefs file has PROGDIR: at the start, then replace that with SketchBlock's absolute path

@broadblues

Just to add to the above, to get the absolute path you just need to call DevNameFromLock() on the lock returned from GetProgramDir().

DevNameFromLock(GetProgramDir(), buffer, buffer_size, DN_FULLPATH);

Sending script commands to ARexx (via arexx.class at least) requires an absolute path to the script.

None of the script locations or any paths are hard coding into SketchBlock they are all setup via the xml prefs file.

But putting <command>SketchBlock:Rexx/SaveAsBrush.rexx</command> in your XML prefs file - as you do - means exactly that: hardcoding it! Instead, you should:

1. Store only the script name in the prefs file, eg. <command>SaveAsBrush.rexx</command>
2. Call IDOS->GetVar("ENV:AppDir/SketchBlock", ... ) to obtain the absolute path to the SketchBlock directory.
3. Construct the full path of the script by appending "Rexx/" and the script name (from the XML file) to the program path obtained in Step 2.
4. Call the script via ARexx.

I can't see why this wouldn't work.

Well I supose that depnds on your definition of "hard coded"

The preferences are entirely user editable, so may be changed to anything the user desires. I'm not sure why you find the sketchblock: assign so problematic, it's not exactly an unheard of concept for apliacation to have a assign to some data directory ot other.

Looking at my assign list I see:


AMISSL         AmigaOS4:Devs/AmiSSL

ANTIWORD       AmigaOS4:Utilities/antiword

Apache         Work:NetApps/Apache-1.3.33

APOD           Work:aPod

ARTEFFECT      Work:ArtEffect4-Demo

AWebPath       Work:NetApps/AWebPPC

AWEB_APL       Work:NetApps/AWebPPC

C4D            Work:Cinema4D

C4DCD          <CINEMA4D_CD-Edition:Bonus>

CVSHOME        AmigaOS4:Home

FreeDB         Music:FreeDB

FTPMountDir    AmigaOS4:FTPMountDir

GCC            Programing:SDK/gcc

GHOSTSCRIPT    AmigaOS4:Utilities/Ghostscript

imagefx4       Work:ImageFX4

MUI            AmigaOS4:MUI

PGP            Work:PGP5

PPaint         Work:ppaint

PYTHON         AmigaOS4:System/Python

TEX            Work:Cinema4D/Textures

TurboPrint     AmigaOS4:TurboPrint

YAM            Work:NetApps/YAM

Some added by me some by the installation processes of those apps, some that come with the system.

I could do some variation on that, I'm not sure using appdir: is reliable for thsi purpose, some users write protect their sys: partitions rendering it inopperable. And I certainly wouldn't hardcode in the Rexx drawer

Well it would in so far as it would launch scripts, but it's not so simple as that. As well as scripts you'll see there are 'commands' in the xml file, these are direct calls to the sketchblock arexx interface.

Given that a script need not have an extention there is no way for me to distinguish commands from scripts (save search my commands list before invoking, but that's allready done bt the ARexx.class, it would be silly to do it twice.

Oh and another thing, ARexx searches for scripts without absolute path name in REXX:
