Re: Starting programming.....

I agree, go for DBAS. But try out a few ideas before you dive into your main application.

Good luck.

Cheers,

Re: Porting PLATOTERM to the QL as a QDOS app.

For the job name: char _prog_name[] = "program_name"; As a global assignment, outside of all functions, including main(). I don't know about there being a channel open but I suspect it's for stdin,stdout,stderr maybe. I suspect, perhaps that this might remove the default channel: char _con...

Re: Starting programming.....

The answer has to be "it depends" and it does depend on what the database is intended to hold. Archive is ok, but has some problems if files are not closed correctly and rumours abound of corrupted databases files for other reasons. I've had a few in my time with nothing more sinister than...

Hi Dave,

When in doubt, Dilwyn's web site is the place to look. :D

Re: Hardware pointers and cursors.

There are countless "PE beginner's guide". One of the more popular is http://www.dilwyn.me.uk/docs/ptr/peig/pe.html . Probably my most popular effort, written way way way back when I still lived in Aberdeen. That was at least 1990, possibly even a little before that. I wrote it because I ...

+1 for Kye, brilliant game which I "lost" many hours playing, and I don't tend to play many games. If I remember correctly, Kye was named after the author's dog which had a tendency to run amok at any time! More here https://en.m.wikipedia.org/wiki/Kye_(video_game) . Cheers, Norm

Re: SCREEN1 = SYSVAR @ JSROM

Hi Tomas,

The composite colours are sent to the traps to change the paper/ink/strip.

It looks like you are trying to plot pixels directly into the screen RAM. In which case, you would need to work out the required dot pattern and colours, then plot those pixels.

Norm.

Re: SCREEN1 = SYSVAR @ JSROM

From Jan Jones: COMPOSITE In order to pass the colour information to QDOS, SuperBASIC has to combine the three components into one composite colour. The composite colour is one byte long: Bit Value 0 1 Bit pattern of main colour 1 2 2 4 3 8 Bitwise XOR of main colour with contrast colour. 4 16 5 32 ...

Re: Symmetric multiprocessing...

What might people do with something loosely based on those types of ideas? Personally, I can't think of anything I could do with this sort of setup. But then again, I could never see that email would catch on, nor did I think that selling pizzas on the High Streets of the UK was a great idea. It's ...
