Re: How t pass arrays into procedures?

Hi Bitseeker

If you don’t have a user guide I have a spare one you can have for p&p. Just let me know if you are interested.

Re: How t pass arrays into procedures?

Thanks for reminding me about that. Someone did mention it before and I had already forgotten! It does actually make sense because when I type say P. on the Beeb or emulator in a BASIC program this does get automatically expended to PRINT when I list the program. Tokenizing makes sense when you hav...

Re: New guy

The beeb speaker often has background noise. I suspect one of the technical people on here can tell you how to sort it - I believe you need to solder a resistor somewhere. For loading and saving I have just ordered two of these:- http://stardot.org.uk/forums/viewtopic.php?f=8&t=12689&start=30

Re: New adventure game and BASIC framework (don’t expect a new Ravenswood)

I have spent additional time looking at where it is slow and while it is down to the conditions it is not down to quantity of them so much as the functions they call when activated so I think this while thing may still be reasonable in BASIC. Although I may need to do the object handling in assembly...

Thanks. Some of it will definitely need to be relaced with machine code, specifically the parser first - that is the slowest part. Packing will help a little and I will give it go.
