When I save a file in turbocalc with an icon, it is saved with the default tool "turbocalc". If I double-click one of these files I just get "unable to open your tool 'turbocalc' I have def_tcd set up in prefs/sys with the full path of turbocalc. If I use the conext menu to open a disk, and select volumes the turbocalc asign is show (in blue below the physical volumes). If I save from turbocalc with out an icon, I get the def icon displayed, and I can double-click the file to load it in turbocalc.
The files with the turbocalc assign used to load into turbocalc automatically, but noe they don't.
Provided TurboCalc actually uses the systems def_tcd.info default icon, try putting TurboCalc:TurboCalc in the default tool.
Could it be possible you have entered the full path wrongly?
In any case, it's pointless to have the assign if you're not going to use it :)
I would suggest using Snoopy when you save a TurboCalc file to see if the def_tcd.info is actually being used...

Turbocalc itself applies the icon, and does not use the def-icon, and hence not the full path of turbocalc. If I tell turbocalc to save without an icon, then the def-icon is used.
The assign in user-startup is there historically, to enable turbocalc files that have a default tool of turbocalc to launch, and be loaded into, turbocalc. I cannot find where turbocalc stores it's default icon, so I can't change that.
The thing is, this used to work fine and now doesn't, and I know some changes have been made to the assign commands, but I don't know what. I would like to find out if I can solve this by changing the assign in post#1, rather than delete all the icon files from the best part of 10 years spreadsheets
Your problem here is the underlying design & age of turbocalc, it was originally written in the age of floppies, the spreadsheets are designed to be saved in the same dir as turbocalc. if you ran out of space you copied the turbocalc floppy and deleted the spreadsheets and started again. which is fine if you have a single floppy system.
The assign is a hack so that turbocalc when installed on a harddrive can find its non-spreadsheet files that were on the "turbocalc" floppy.
The first thing you need to do is upgrae to turbocalc 5 which should be easy enough, there are copies around the net and as digita no longer give a monkeys about amiga stuff you might as well grab a copy.
Next thing to do is change the way you use turbocalc, stick it in amidock and use the "open" menu instead of hunting through years worth of spreadsheet icons. Don't forget about the "autoopen" drawer if you use the same spreadsheet most of the time.
Btw. the default icon is stored internally so you cannot easily edit it unless you really know what your doing

You are assigning to the program not it's location (unless you do actually have a tubocalc drawer within a turbocalc drawer).
OK, that worked, thanks.
I can't help but think that this is a backward step in AmigaDOS though.
Previously (3.1, 3.5, 3.9, etc) the following worked:- Assign TurboCalc: Work2:TurboCal/Turbocalc
I assume the colon after the first Turbocalc sets this up as a device as far as AmigaDOS is concerned. As you say this is actually assigning a program to Turbocalc: (a pseudo device). Now, we have to make the assign to a drawer, and then add that drawer to the search path. Two steps instead of one, and also a break in compatibility.
My user-startup, because of transfering/upgrading from my A1200, is 152 lines long, assuming five lines (approx) to an assign, that is a lot of assigns to change. From a DOS point of view, I can see the reasoning behind not assigning a program to a (psuedo) device, but wouldn't it just be easier to automatically add the assign to the search path automatically. I am not that up on using AmigaDOS, but I can't see where you would need to make an assign that isn't added to the path, as that is surely the point of the assign.

Assign is nothing to do with floppies, although it can be used to launch an application by double-clicking on a project file that resides on a floppy. The assign is a system mechanism, by which I can double click any project file at any location, and it will open that file in it's mother application. This is the same for Wordworth, Finalwriter, Pagestream, and any other application that I use on my Amiga. It means convenience, it means, I don't get annoying system requester's asking me to select which program to associate this type of file with (windows). The assign function forms this association automatically on a file by file basis and not on a file type basis. It is one of the reasons IMHO that AmigaOS is easier to use than windows.
Assign IS all to do with floppies and the limited storage space they have. it was originally designed to allow you to have data files spread over many floppies without having the problems caused by identical floppy names. and very useful it was with KS 1 & 2.
Many programmers used assigns to easily add harddrive support to programs that were originally designed to run from floppies. eg. protext had 3 disks so installing all three to the same place and assigning the floppy names to that place made it work. Assigns are to tell programs where their files are, the fact that you think "The assign is a system mechanism, by which I can double click any project file at any location, and it will open that file in it's mother application." has nothing to do with it. most project icons don't have an assigned path in them by default. Most programs use the internal PROGDIR: assign. The 'System Mechanism' that allows you to do that is the 'Default Tool' option itself.

Assignments pointing to files are still working in OS4. The error message comes from the Path command which does not allow to add files to the path list (which would not make sense).
Assignments pointing to files are still working in OS4. The error message comes from the Path command which does not allow to add files to the path list (which would not make sense).
Why do I need to use the path command? Why does the assign command not work without it? Why did my previos assign not work? Why did I get an error message when double-clicking on a project icon?
The only way to get the double-clicking to work, with the same result as previous OS versions, was to add a path command, and remove the file from the end of the assign. If an assign is (under OS4) not automatically added to the path, how is that an improvement? The whole point of an assign is that AmigaDOS is aware of the assignment. Regardless, of whether the assign command was developed for floppies, its main use is by programs adding an assign to user-startup when they are installed, to make the OS aware of where they are located. If that now doesn't work, without using a second (path) command it seems a backward step IMO. I am not trying to be a pain. I am just trying to understand why such a change has been made. If it hasn't been changed, what is the correct syntax of the assign command, that will correct my error messsage without requiring the use of the path command.
I could be wrong, but as I understand it, the "Assign" command and the "path" command are different in purpose.
"Assign" allows you to assign a device name (ending in a colon) to a directory. Great for getting organized, great for naming a point so programs can find it ("SDK:"), also great for copying the contents of a floppy onto a HD, as mentioned before. But as far as I know, it has nothing to do with the search path for commands, unless your icon or command line is calling with the included device name and path. ("SDK:include_h/amiga_compiler.h")
I just read the "AmigaDos" book.. It seems to agree. "Assign" is cool, and allows multiple assigns and tests and such, but it does not appear to affect the path.
If I'm wrong, please teach me more. I'm always ready to learn.
Your icon has "TurboCalc" as default tool. Without path. Then Workbench will search TurboCalc in the current directory (where the project file is located) first and fall back to the search path which is defined by the Path commands in Startup-Sequence and User-Startup.
When it worked before, either your project file was located in the same directory as TurboCalc, or your S-S and U-S defined a search path that included the directory which contained TurboCalc, or your icons contained the full path to TurboCalc.

The Assign command is something completely different than the Path command.
Quote:

It worked. It just did not have any effect on the search path...
Quote:

Because Workbench could not find TurboCalc in the current directory or in the search path.

Yes. Because it has nothing to do with the Assign command.

No need to ask for an improvement. It works as before.

Right. Partly. Assigns are not only used for locating programs but also for locating data. There e.g. exist FONTS: LOCALE: PRINTERS: CLASSES: HELP: LIBS:
Quote:

There was nothing changed. Ergo no step backward happened. Even OS3 was smart enough to NOT waste time by searching a program in FONTS: or LOCALE: ...

No change happened.

There exists no possibility to use the Assign command to change the search path for programs. The Path command is used to specify the search path. Ok, an indirect possibility exists, by modifying assigns which are part of the search path.

I think you are mixing things, the ASSIGN command never was about adding search paths to the system (obviously it was the PATH command that was designed for that). AmigaDOS is fully aware of you assign, even under AOS4, just type in a shell :
Multiview Short:MUI.guide
this should not work
ASSIGN Short: Sys:MUI/Docs/English
nothing happens, now retype
Multiview Short:MUI.guide
now this should work.
In fact what you did is assigning to Sys:MUI/Docs/English the logical name Short: You can see that as virtual drives or subst under Windows. This is also a way to address by the same absolute path something that may be anywhere without knowing the exact position (for example my virtual TurboCalc: assign points to DH1:Bureautic/TurboCalc5 on my setup, but I know that if I type TurboCalc: I would go to that place witout the need to remember the exact place).
Hi Detlef, thanks for the extensive reply. I do have one query however.

1. Project file is in a seperate directory 2. User-startup = Assign TurboCalc: Work2:TurboCalc/TurboCalc 3. The icon does not contain the full path.
Only item 2 is a possible reason for the assign to work, and it doesn't, without the addition of 'path turbocalc ADD'. This used to work on my A1200, in fact I copied my A1200 user-startup when I moved over to OS4. I think I need to boot up the A1200 and start looking at this from there. Anyway, thanks for your help, I'll have a play and come back to you.
With this assign (assign pointing to the exe file itself) it would probably work if you typed TurboCalc: (note the colon character) into the default tool field. Then you wouldn't need the path command but you would have to edit the default tool field on all your files.
The assign command creates something like a logical alias. The alias name is called TurboCalc: (with colon !). If you want to refer to the alias you have to use the full name TurboCalc: (with colon).
So you can create an alias for a directory
assign TurboCalc: Work2:TurboCalc
Now you can refer to the directory as TurboCalc: and to the program as TurboCalc:TurboCalc.
Or you can create an alias for a file
assign TurboCalc: Work2:TurboCalc/TurboCalc
Now you can refer to the file as TurboCalc: (with colon). You cannot refer to it as TurboCalc (without colon).
This means, if you want to point your project icons to the assign, the project icons have to have TurboCalc: (with colon !) as default tool.
If you want to refer to TurboCalc without colon as default tool, then assign is not the tool to use. In this case you should add the directory where TurboCalc is in to the system path and remove the assign alltogether.
user-startup:
path add Work2:TurboCalc
Then you can use "TurboCalc" without colon and without absolute path as default tool.
IMHO assigns to files are something strange and shouldn't be used.
