I have comments below, but first... function ltrim(sequence string) if string[1] =3D ' ' then string =3D string[2..length(string)] else return string end if ltrim(string) end function function rtrim(sequence string) if string[length(string)] =3D ' ' then string =3D string[1..length(string)-1] else return string end if ltrim(string) end function Euphoria is good. Just ask, I was put in awe at first because I thought Euphoria couldn't do something, but its always proven me wrong. In QBasi= c, Q stands for Quirk. QuirkBasic has many quirks. I'm taking a high schoo= l class on it, so I should know. Look at the for...next loops and variable= initializations, to name a few. I'm not saying Euphoria is perfect, absolutely not. But its better than QBasic. --Alan =

how come Euphoria programmer absolutely HATE basic??? basic lets you do lots of things. Look: object command command=command_line() command=command[3] if nothing was typed at the command line, then you get an error message. in quickbasic, command$ returns "". No errors at all. But Euphoria can check multiple parameters, but quickbasic can't. so they both have their share of quirks. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

Hi, -----Original Message----- From: Matt Z Nunyabidness <matt1421 at JUNO.COM> To: EUPHORIA at LISTSERV.MUOHIO.EDU <EUPHORIA at LISTSERV.MUOHIO.EDU> Date: Saturday, September 19, 1998 12:52 PM Subject: Re: regarde et apprend, watch and listen >how come Euphoria programmer absolutely HATE basic??? basic lets you do >lots of things. Look: I don't hate Basic. I make a good living programming in it. I *hate* C. Euporia has a great syntax and is very flexible. That's what I love about it. I would really like to see a better way to trap errors better than just crashing. Of course some things should bomb out, but I like to be able to trap for some things. (Mainly in Windows programming) Strutures for Windows API programming would be great too. (Probably get lots of flames, but it's just IMHO) Regards, Greg Harris HHS

>how come Euphoria programmer absolutely HATE basic??? basic lets you do >lots of things. Look: Why do we hate basic ? The best reason is it eats out of your brain, and makes you think weird dumb silly things.. Just consider the problems you've been having with Euphoria.. you were trying to solve things the basic-way.. while in euphoria you have a few small powerfull tools, which you can use to make your own solution to problems, instead of using a specific function or routine.. (something you were automatically looking for.. as an example of how basic corrupts a mind).. no offense, we've all been there.. but try not to think in Basic.. or compare euphoria to basic.. Its not just euphorians, c programmers also, or to put it differently: any professional programmer, and about half (upper half) of the hobbiests.. Meet the world.. any hobbist spending more than half an hour a day to programming either hates basic or has no other programming language available for his use. (the above statements exclude visual basic, which due to its nice GUI-design interface, still beats Euphoria win32.. face it.. basic sux, but Eu-win32 doesnt even exist for real) And now this: >object command >command=command_line() >command=command[3] > >if nothing was typed at the command line, then you get an error message. >in quickbasic, command$ returns "". No errors at all. But Euphoria can >check multiple parameters, but quickbasic can't. so they both have their >share of quirks. You totally missed the point. This is one of the example, why Euphoria rules over Basic: Basic lets all the argument parsing up to you. If you would do: mid$ (command$ (), 1, len(command$)) it will also crash basic. You comparing to completely different things. Try making a safe example program of echo the number of arguments passes: example: myprog bla bla Prints "2" Try making this in basic, and euphoria, and both need to work 100% safe.. Compare the code for each.. I rest my case.. Plus, btw.. your program above asumes some1 at least gave three arguments.. thats why things went wrong.. compare it to this basic statement: print mid$ ( command$ , 1, 12) It assumes a minimum of 12 character long command$.. and will crash as well.. In other words.. what is your point ?

besides, my goal is to be multilingual, even though i may forget BASIC. Shameful, I get so good at it, then Euphoria sidetracks me and i forget the language i love. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

i want to see an example of save_text_image to save a snapshot of the screen, save the resulting sequence into a file, and use another program to bring it back. I tried that, but in the process of displaying it with display_text_image, Euphoria says something about not defining the length of an atom. I think it reads: "Length of atom not defined". _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

the first two arguments are always filled with SOMETHING. when a program is not bound, command() passes: {"ex", "myprog.ex", "blah", "blah", "blah"} When you bind it, it reads: {"myprog", --replaces ex.exe "myprog", "blah", "blah", "blah"} Suppose this is what command() looks like: {"ex", "myprog.ex"} And you try to read from the third argument where the stuff you supply on the command line starts, but nothing is there. You get an error from Euphoria. Btw, i'm a former BASIC programmer that's fed up with the way Euphoria sometimes just won't do what i tell it to. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

Shameful, I get so good at it, then Euphoria sidetracks me and i forget the language i love. <<<<< Being multi-linqual is good. That's my goal as well. But let me ask you= =2E = Do you really want to remember all those reserved strings, like inkey$, f= or the rest of your life? I encourage you to use the best programming language for the task. Sometimes it'll be Basic, sometimes it'll be Euphoria. My problem with Basic is that it has too many functions, statements, keywords. Do you know how many of those I know how to use? less than 10= %, I'd bet. But I have the capacity to use the language definition of Euphoria, because I know it all. Now, what about the 133 library routine= s? command_line() clear_screen() time() tick_rate() sound() set_rand() rand() sin() cos() tan() puts() print() ? close() where() seek() trace() Well, that's more than 10% of the nitty-gritty routines already. Some things, though are difficult to do in Euphoria. QBASIC sound 5000, 18.2 sleep 1 sound 5000, 18.2 In Euphoria, I have to hop, skip, and jump to do that. So I say again, u= se the best language for the situation. --Alan =

Two, very clean, easy to understand, programs are attached. One saves the image, the other loads it back up and shows it. If the filename is not given as an argument, it is prompted for. We'll be using Jiri's trim function (mine only handles spaces) to clean up the filename. We'll be using standard I/O to save and store whole euphoria objects. The program looks big, but thats just because this is the cleanest best, approuch. It could have been done in 5 lines, I guess. Anyways, I hope these will help you..

in Euphoria you have to have a sound statement in a for loop, other wise the sound you're making will never end. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

there's nothing wrong with the way BASIC handles a FOR loop.

Just one thing. I needed a program that reads a sequence made by save_text_image from a file, and then uses display_text_image to use it. BTW, i accidentally deleted your message, can you resend it?

Matt, Matt, and Matt This works. I know because I just finished a program on it. It counts down from 5 to 1, then stops for 60 seconds. ie. snippet from pulse.ex for i =3D 5 to 1 by -1 do machine_proc(1,7500) t =3D time() + 0.1 while time() < t do end while machine_proc(1,0) t =3D time() + 0.9 while time() < t do end while end for Don't worry about whats in the for. Its unconventional for Euphoria, bu= t I used it to avoid includes for speed. Its not what one should write in normal cases. --Alan =
