Greetings.

You have done great job of making realy briliant, simple and effective programing language. I like it very much. But I have some questions. Please do a favor and answer them.

1. I have not noticed a switch/caseof instruction. May be it will be helpfull to offer it in future releases? 2. The most wanted thing - embeded euphoria mod for apache. You know, many of us will be happy to write euphoria-powered web-aplication. Just like that: <?eu ... ?>

I also wondered about the advantage of having a Euphoria mod, but I wouldn't know the first thing on how to get that done. So...

I've got a few sites being served up via Euphoria+Apache:

If you want to help with or take a look at BBCMF, let me know!

The new 4.0 (not yet released) has a switch statement now in addition to many, many useful features including a vastly expanded standard library. A mod_euphoria is a pretty hard task due to how Euphoria works internally. We do, however, have other web capabilities. I personally am working on a SCGI interface for Euphoria which will allow for stateful Euphoria applications that should run on many web servers such as Apache, LigHTTPD, IIS and other popular ones. This will allow for very fast web apps written in Euphoria, both interpreted and compiled. I think once you get your app debugged you will want to make use of the translator which will take Euphoria code and convert it to C. With a mod_euphoria or something similar, you would not be able to take advantage of this great feature of Euphoria.

I don't understand the label part or how to use it. Nothing in the docs explains it. The example doesn't use it.

switch <expr> [label "<label name>"] do

switch foo label "SW1" do 
   case "A" : 
       switch bar do: 
          case 1: 
              dosomething 
              -- The 'break' here let's me get out of the enclosing switch. 
              if x then break "SW1" end if 
              break 
          case 2: 
              . . . 
       end switch 
   case "B": 
         . . . 
end switch

See the section about "labelled headers". if, switch, while, for and loop all may have a label into the header, which some control flow instructions can use.

Like in

while 1 label "top_ loop" do 
  -- something 
  for idx = 1 to whatever do 
    if something_happened() then 
      exit "top loop" -- this gets out of the while loop with that label 
                      -- you could also say exit 2 or exit 0, but they are less easy to maintain. 
                      -- you cannot use anything variable here 
    end if 
  end for 
end while
