#includestdio.h

char*X,*B,*L,I[99];M,W,V;D() {W==9?(w(`%.*s' is ,V,X),t(0):W==40?

Though one must say that these programs are usually not written this
way, they're written more readable and obfuscated afterwards,
sometimes even using specialized obfuscation programs.
In any case, here's a C68 compatible entry:
#includestdio.h
main(){int i=0;while(i++100)printf(%i %s%s\n,i,i%3?:FIZZ,i%5?:BUZZ);}
Pretty straight forward and not really original, but still not that
easy to beat I guess.
On the web there are mighty crazy FIZZBUZZ programs available, but
they use slightly different rules in that they do not print the number
if FIZZ, BUZZ or both are written, which makes things a bit more
complicated.

Re: [Ql-Users] QL on 2 monitors
Dilwyn, I have a Vista dual screen setup at my office and at least QPC2 works perfectly with it. And yes, you simply drag the QL window to the monitor of choice. This obviously doesn't work in full-screen mode, but full-screen doesn't work well on modern LCD screens anyhow because they don't scale well. I have that problem using the Aurora in some resolutions with an LCD screen. Looks worst with text, because individual horizontal lines get repeated and makes text look really bad. Guess it's even worse for Q40 users with the 2:1 1024x512 pixel modes. At least some Aurora modes look not too bad on a 14 inch non-widescreen monitor I use with the Aurora. You do have to choose the right modes to suit the monitor, though, or it looks awful. If I remember right, QPC2 uses the main monitor in full-screen mode. No idea how the other emulators cope, however - if they use a windowed mode, I see no reson why it shouldn't work as well. Tobias Thank you both (George and Tobias) for your replies. I knew QPC2 could, because when I had my eeePC notebook (which is now living in West Ireland last I heard of it!) I was able to use QPC2 on either screen with that, although I couldn't remember how to go about it. I was using it when my son and I made the 25th anniversary QL presentation for Quanta. Annoyingly, the Powerpoint viewer I used for running that demo would only run on the first screen, so I had to have QPC2 on the second monitor at the time. But I don't remember using QL2K or Q-emuLator like that. They can both run in windowed modes, so I guess SHOULD work (if anyone can confirm that?) And, no, I don't use it to hide my QPC windows ;-). Dual screen is just a charm to work with when you're doing several things in parallel, like preparing graphics using windows that you want to use on the QL side. Yes, of course - I must investigate whether my current laptop can handle 2 monitors, as I know the graphics card on this PC has only one video output. The eeePC could use its own screen as monitor one and an external monitor could be (1) in place of the internal screen (internal screen disabled), (2) duplicate the internal screen, or (3) be an external second screen which was not the same as what was displayed on the inbuilt monitor. Actually, (3) sort of worked in reverse for me on the eeePC, because it was possible to do more intricate work on the larger external monitor and leave things like Outlook running on the smaller screen, which was good enough to see when email arrived and so on. I remember the 14 inch monitor being stood behind the eeePC on top of a pile of books so I could see one display above the other without turning my head to see what I was typing! I seem to remember that some apps will let you drag and drop from programs running on one screen to programs running on another, which is great.

[Ql-Users] Q-emuLator
Um, a question from me this time... Anyone know if Q-emuLator can print to a printer on a USB port? As far as I can see it seems to be only possible to print to a parallel LPT port on the PC, or in some cases a serial port printer if using the emulation mode. (Am busy testing Quanta library submissions using Q-emuLator as a QDOS QL to test the programs, but can't seem to get anything to print). Actually, quite an exercise in itself running QPC and Q-emuLator at the same time...for example, when both are trying to access the same floppy disk!

Dilwyn, get out from under your desk, I can't, I'm stuck in an endless tangle of zip-tied cables :-) keep that printer connected to USB, get yourself a comfy place somewhere and read the QPCPrint Manual, especialy the chapter Installing QPCPrint as a virtual printer. This talks about a technique how you can have hour USB printer emulate an LPT: printer. It installs a new LPTx: (i.e. without hardware), whatever you send there is then filtered through QPCPrint and sent to the USB printer. I think that's exactly what you're looking for. Cheers, Tobias Except (1) I never needed QPCprint with QPC, so (2) I never bought it, so (3) I don't have it! Ahh, got it. I somehow was under the impression that nowadays everyone would need/have QPCPrint. Definitely a serious omission from your software library. QPC printing works fine for me without QpcPrint. I want to see if QemuLator to do the same thing! What you could try (After you managed to entangle yourself from under the desk) : Export your USB printer as network printer. Go to a terminal session and redirect LPT3 (or whatever your first unavailable LPT: is to that network enabled printer with net use LPT3: \\yourcomputername\usbprintername Voila, you've got your USB printer on LPT Cheers, Tobias ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
Re: [Ql-Users] Hard directories
If you use WinBack to create a backup, there was a (useful) utility which took a snapshot of the directory structure, built a new SuperBasic file (called Make_directory_bas I think) and you would run this first against a new disk prior to a restore. It made life easier as the restore would put the files back into the correct location, as opposed to having all the files live in the top level directory and then make_dir everything afterwards. That way of doing it resulted in huge piles of holes in the directory structure and doing DIR WIN1_ would result in quite a substantial delay as the DIR code skipped over all the holes. Of course, if you didn't use WinBack's utility to build the tree, then you are slightly stuffed I'm afraid. :-( Cheers, Norman. -- Norman Dunbar Dunbar IT Consultants Ltd Registered address: Thorpe House 61 Richardshaw Lane Pudsey West Yorkshire United Kingdom LS28 7EL Company Number: 05132767 ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Not declaring a function, even one returning int (the default return type) is listed in my book of common C mistakes. Main() always returns int. Main always takes two parameters int and char **. It should, to generate anything maintainable, but doesn't need to. C allows you to ignore return values. I know it allows me to do so, but just because I can do something doesn't mean that I should! ;-) Seriously, I agree. But the fact that main() is not returning a value is not the same as ignoring one, because it's the OS that should get the return from main() not some other part of the C program itself - which happily lets you, as you say, ignore return values. I can do even better (alas, not on the QL - And: I'll probably never get employment as a Java programmer): Neither will I I'm afraid, I loathe and detest Java with a vengeance! Too many problems at work caused by too many [bloody] java programmers (I use the term loosely) who reinvent the bloody wheel in java every single program they ever write. Sometimes I despair! I wonder how the fizzbuzz program would be written using quantum computing - which knows all the answers before you even ask the question!

Re: [Ql-Users] Q-emuLator
Great - thanks Rich. It never occurred to me that QPCprint could be used with anything other than QPC2! (Oops sorry Tony, just realised too late I've top-posted) Dilwyn Jones - Original Message - From: Rich Mellor r...@rwapservices.co.uk To: ql-us...@q-v-d.com Sent: Sunday, November 28, 2010 8:28 PM Subject: Re: [Ql-Users] Q-emuLator QPC works because it allows you to set any PC port as the port seen by the PAR command on the QL emulator. So far as I know, there is no such option in q-emulator, although this is something I have never had to look for. QPCPrint can be used to capture the output from any QL emulator, or other program running on the PC - it does this by setting up a virtual printer driver which captures the LPT1 port and then uses the Windows printer processor to send the output to any connected printer. Printfil is something similar - both programs are detailed with links on www.rwapsoftware.co.uk/Printers2.html as an option for emulator users. The other option is to investigate other options for capturing the LPT1 port and redirecting output - a good guide appears at: http://geekswithblogs.net/dtotzke/articles/26204.aspx Read this in conjunction with the step by step guide on the QPCPrint site if you want more details - http://www.kilgus.net/qpcprint/printer.html There are others out there also - DOS2USB for example (I have never tried this) - but no free solutions unless you follow the examples listed above Rich www.rwapsoftware.co.uk ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
