yes, tons http://oe.cowgar.com/docs/eu400_0111.html#_5856_changes

All the demos included with version 3

The key thing here is not to worry to much. You're no longer constrained by having to put a called procedure BEDORE you call it within the program. I still try to, because its habit and discipline, and when I do call one forward, I put a little comment in it to tell me where it is in the future - happens rarely though.

One of the biggest, and most convenient changes, is not having to assign a variable to a function when returning. For instance I have a get_yn_box function, which I used to have to assign to VOID variable on return, but now I can just call the function as if it were a procedure. Almost does away with the requirements for procedures.

Incidentally, you needn't have set up two users, having to switch between users in order to use eu 4. Eu 4 doesn't need environment variables to be set any more (just a path to eui, and as exw/ex are eu 3 programs, there is a different call to start them), look up eu.cfg, which replaces the environment variables http://oe.cowgar.com/docs/eu400_0011.html#_64_eucfg

Maybe because there's no get_i_could_care_less_box function? :)

LOL

Because it also became a "Hit any key", and "You can't do that!" message box function

LOL ... This is another Americanism that has amused me for awhile. They tend to say "I could care less" when they actually mean the opposite "I could not care less".

Yes, but I would assume that these are ver3 demos.

What I would like to see is demos that work in ver4 but will not work in ver3.

Thank you for that.

So Ver3 must use Environmental Variables.

If running two versions I need 2 EUDIRs:
Ver3 = "E:\euphoria"
Ver4 = "E:\euphoria-40B4"

Each with their own include files.

Also 2 PATHs:

Ver3 = "E:\euphoria\bin"
Ver4 = "E:\euphoria-40B4\bin"

If using only one set of Environmental Variables (remember you must have 1 set for ver3)

Let's say using the extention .exw, how would Euphoria know what to use exw.exe or .eui.exe?

Don Cole

@PATH=%PATH%;C:\euphoria40b4\bin;C:\euphoria40b4\include 
@SET EUDIR=C:\euphoria40b4 
@start /b C:\euphoria40b4\bin\eui.exe %1 %2 %3 %4 %5 %6 %7 %8 %9 
@cls

Hi

Yes, that's another solution.

Sorry Don, if you want the ease of clicking the .exw program to start euphoria, then you can only choose either eu4 or eu3 (or use your 2 user solution). To run eu4, as Kat says, rename the extension of the program you want to run to .eui, and associate it with eu4. BUT the environment variables will be used by 4, which is why you use a .cfg file, to search for eu4's include path first

If you want the choice of either running eu4 or eu3, then you either have to use the batch solution, or ensure that a eu.cfg file exists in the program_that_you_are_writing's folder. The environment variables are only required for eu3 (yes you must have them), but are optional for eu4 if you have a eu.cfg in the folder.

Alternatively, do as I have done, and dump eu3 entirely. Make's life so much more simpler, and haven't found a program yet I can't tweak up to 4's standard. Part of the fun.

There is yet another way. Here is a .reg file from Edita:

REGEDIT4 
 
[HKEY_CLASSES_ROOT\.e] 
@="Eu DOS include" 
[HKEY_CLASSES_ROOT\EU DOS include\DefaultIcon] 
@="E:\\Euphoria\\BIN\\Ex.exe,1" 
[HKEY_CLASSES_ROOT\EU DOS include\shell\open\command] 
@="E:\\Euphoria\\bin\\exw.exe D:\\Edita\\Edita.exw \"%1\"" 
 
[HKEY_CLASSES_ROOT\.ex] 
@="Eu DOS program" 
[HKEY_CLASSES_ROOT\EU DOS program\DefaultIcon] 
@="E:\\Euphoria\\BIN\\Ex.exe,1" 
[HKEY_CLASSES_ROOT\EU DOS program\shell\open\command] 
@="E:\\Euphoria\\bin\\ex.exe \"%1\"" 
[HKEY_CLASSES_ROOT\EU DOS program\shell\edit\command] 
@="E:\\Euphoria\\bin\\exw.exe D:\\Edita\\Edita.exw \"%1\"" 
 
[HKEY_CLASSES_ROOT\.ew] 
@="Eu Win include" 
[HKEY_CLASSES_ROOT\EU Win include\DefaultIcon] 
@="E:\\Euphoria\\BIN\\Exw.exe,1" 
[HKEY_CLASSES_ROOT\EU Win include\shell\open\command] 
@="E:\\Euphoria\\bin\\exw.exe D:\\Edita\\Edita.exw \"%1\"" 
 
[HKEY_CLASSES_ROOT\.exw] 
@="Eu Win program" 
[HKEY_CLASSES_ROOT\EU Win program\DefaultIcon] 
@="E:\\Euphoria\\BIN\\Exw.exe,1" 
[HKEY_CLASSES_ROOT\EU Win program\shell\open\command] 
@="E:\\Euphoria\\bin\\exw.exe \"%1\"" 
[HKEY_CLASSES_ROOT\EU Win program\shell\edit\command] 
@="E:\\Euphoria\\bin\\exw.exe D:\\Edita\\Edita.exw \"%1\"" 

and here is another, less scary, one I found lying around:

REGEDIT4 
 
[HKEY_CLASSES_ROOT\.exw] 
@="EuWinApp" 
 
[HKEY_CLASSES_ROOT\EuWinApp] 
@="Euphoria Windows App" 
 
[HKEY_CLASSES_ROOT\EuWinApp\DefaultIcon] 
@="C:\\Programs\\Euphoria\\Bin\\exw.exe,0" 
 
[HKEY_CLASSES_ROOT\EuWinApp\shell\open\command] 
@="\"C:\\Programs\\Euphoria\\Bin\\exw.exe\" \"%1\"" 

It would not be difficult to create say Eu3.reg and Eu4.reg versions of these which would allow you to right-click on them and select Merge to alter Windows behaviour, nor would it be difficult to knock up a simple gui front-end to double check everything, make backups of existing keys if required, and display a couple of buttons you can click. With a bit of luck, all the icons would change so you would always know exactly where you are at.

Be warned that I haven't actually tried this, and you may need a 4.0 .cfg file to get the includes right, but I'm convinced it could be made to work, and quite slickly too.

Regards, Pete

Thank you Kat, ChrisB, Irv, Pete and Matt.

Kat, Thank you, I'm sure your way will work but involves changing the name of all my ver3 or ver4 program file extensions.

Chris and Irv, Convert to 4 and dump 3 is a good idea. But all the programs I have written since 1998 are in ver 3. And they are working. I see no need to muck them up. So until I convert everything to 4(which may take a couple of years) I want keep 3 intact.

Pete, your way involves changing the registry. Something I'm not crazy about doing. BTW the way I use Edita in my two user configuration is I use two instances of Edita located on different drives. And set the ver3 file extensions to .exw and ver4 file extensions to .eui.

Matt, The config file would need some studying to set up, I'm lazy.

Chris, I'm going along with you and using the two user system. It doesn't require any further setting up.

Again I want to thank everybody for their help.

18. Simple way to use both versions 3.1 and 4.0

Here is a very simple (but practical) way to use both Euphoria version 3.1 and version 4.0:

1. Install version 3.1 in "C:\EU3"
2. Install version 4.0 in "C:\EU4"
3. Set EUDIR=C:\EU
4. Set PATH=%PATH%;C:\EU

5. Now, when you want to use version 3.1 - rename "C:\EU3" to "C:\EU";
and, when you want to use version 4.0 - rename "C:\EU" back to "C:\EU3" and rename "C:\EU4" to "C:\EU"...
and so on.

It is very quick. You don't have to change any environment variables or create another user or a special batch file. And it works.

.ex="e"\\euphoria\\bin\\ex.exe"--ver3 files 
.exw="e:\\euphoria\\bin\\exw.exe"--ver3 files 
.exwc--I really don't know what this is for. I'm using it as a dummy extention to run my ver4 files.  
.exec="e:\\euphoria-40B3\\bin\\celibate" 
</encode> 
  
That .bat file looks like this: 
 
<encode}> 
@@PATH=%PATH% E:\euphoria-40b4\bin--change the Environmental Variable PATH. 
@SET EUDIR=E:\euphoria-40b4       --change the Environmental Variable EUDIR. 
@SET EUINC=E:\euphoria-40b4\include;E:\eu\myinclude;e:\eu\football;e:\eu\win32lib--change the Environmental Variable EUINC. 
@start /b E:\euphoria-40b4\bin\eui.exe %1 %2 %3 %4 %5 %6 %7 %8 %9 --start the ver4 eui.exe.

All the 3.1 demos have been upgraded to 4.0. 4.0 also includes quite a few new demos in the demos/ directory that are 4.0 specific.
