BASIC Ten-Liners Contest 2015

Recommended Posts

"Write a game in 10 lines of BASIC!"

For the fourth time this is the motto of the programming contest on the occasion of the retro computer meeting NOMAM. In the years 2011 and 2013 the BASIC Tenliners compo was a small internal competition and the programs were made live at the meeting. In contrast, in 2014 contributions from all over the world came. And only one contribution was produced live at the meeting. Over ABBUC and AtariAge forums the incredible amount of 40 games from Australia, USA, Chile, Poland, United Kingdom and Germany rolled in.

This year we want to give the competition a new impetus by opening it; both in terms of legal systems, as well as with regard to authorized BASIC dialects.

Legal systems:

Atari 8-Bit

Commodore 64

Commodore 128

Schneider CPC

Authorized BASIC dialects:

Atari BASIC (A8)

Turbo BASIC XL (A8)

Altirra BASIC (A8)

OSS BASIC XE (A8)

OSS BASIC XL (A8)

Commodore BASIC V2 (C64)

Simon's BASIC (C64)

Commodore BASIC 7.0 (C128)

Locomotive BASIC 1.0 (Schneider CPC)

Locomotive BASIC 1.1 (Schneider CPC)

Other BASIC dialects and computer systems are approved under the condition that the contributions will be presented by the programmer on the original hardware at the NOMAM (04.11.) in Lübeck.


Even if the fun of programming and the competition should be in the foreground, but a few rules are needed.

Contributions are accepted in three different categories:

Category "PUR":

Program a game in 10 lines (max. 120 characters per logical line, abbreviations are allowed)

Category "EXTREM":

Program a game in 10 lines (max. 256 characters per logical line, abbreviations are allowed)

Category "LIVE":

On 04/11/15 a programming assignment is made, which must be resolved within 2 hours

Further rules:
- No reloading of data or program parts
- Call of machine language programs are prohibited
- POKEing is allowed (eg change the DL, PM-graphic)
- Deadline: Saturday 04/11 at 9 pm (Central European Summer Time) (Remote posts: Wednesday 04/08, 9 pm)
- Voting: Saturday 04/11 at 11.30 pm, then awarding
- Together with the program a text file should be submitted with the program description and instructions
- The programmers agree to the publication of the programs, the description and the instructions by the organizer
- Only physically Attendants may vote
- Remote contributions, however, are permitted provided they are received by Wednesday, 04/08 at 9 pm at GKANOLD-ät-GMAIL dot COM

Sikor, as you like. I will check regularly AtariAge and ABBUC forums and of course also my Email account. Some people sent me their contributions per mail other attached it here. I think, both is okay. I don't know if there will be any interest at other retro systems, I will inform you...

And remember - use unprotect disk (or option R/W in emulator).

 

I think that's the point. R/O (read only) is standard option in Altirra. You have to change it to R/W (read/write). I remember this was my common mistake using this emulator first times.

There were some discussions with the Amstrad and the C64 community (cpcwiki.eu and forum64.de).

 

Issue 2 of "further rules" were misleading. So it will be changed to:

 

- the 10 lines of the programm can not contain self-written machine code

 

Unfortunately I am not able to edit the first post.

Probably a good idea to publicise it at Lemon64.com as well - it's probably the biggest C64 forum.

 

I'll try and get in again, hopefully with more entries, and take advantage of TBXL this time.

C64 would be really interesting given the 80 char/line limit and somewhat simpler Basic. But I suspect we could implement similar tricks to A8 to cram more into each line.

Good point. I remember, when I organized "5zł compo" at atarionline.pl - Magnus (Zenon Mikołajczyk) code all in ain assembler after REM lines ;) In 10 lines - as here (I'll must find disk with this some time and put it here for good example of this problem).

Oh good, this is back! I was wondering.

 

My a8 died last year, so I may request some real hardware testing over in the dev forum, but I've got a solid chunk of vacation coming up around mardi gras again that I can sit down and hopefully put something nice out. I'm thinking something more 2-player this time, but I have to come up with a creative way to do that using little space.

 

If the Commodore/Amstrad folks really get in on it, there could be quite a few entries, indeed. I'm pretty interested in seeing how the basics stack up against eachother. How you guys find time to do anything at your gathering besides judge 10-liners is beyond me.

is X=USR(ADR("hLVd")) type thing allowed to call SIO or other OS routines allowed?

Nope. No machine code. That string contains machine code.

You can possibly though use the dirty DOS trick - set up dosvec and call DOS. No self-written machine code.

 

A different question - screenshots only pre meeting this year?

 

Best,

Any limits on controllers?

No. I'm thinking about using my android phone as touch controller...
