Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Geoff,
"AUTO" command is not reset by "NEW" or "CLEAR" etc.
Do we have to set it to line number "10" everytime or something else.

You are right, it should reset on the NEW command. I will fix that in the next version.

In the meantime you will have to explicitly reset it with AUTO 10, 10

Geoff,

101 things... Can the current program name in memory be returned in a Predefined Variable, say mm.sav. In my case I would add it to my command prompt string and may one day prevent a accidental save to the wrong name.

Thanks,
Anthony.

What a neat idea. OK, I will add that in.

Hi Geoff,
I'm really enjoying playing with the Maximite, and dusting off the brain cells I used on GWBasic 25 years ago. Fantastic job - well done.

In 2.6 have you changed the amount of memory available to Arrays? Since I upgraded from 2.5 to 2.6D, my arrays (38k reported in 2.5) don't fit. So here are a couple more questions along similar lines for future releases:

- any chance of making the memory allocation configurable between program, variables and arrays?
- any chance of introducing random access mode for files as in GW Basic; i.e. so I can specify the line number to be read in a file?

Cheers,
Greg

Yes, I did reduce the memory allocated to arrays by a small amount. I did not think that anyone was using the full extent of that memory but obviously I was wrong.

Also yes, better memory management is on my todo list. It will not make a huge difference to most users but it will help when memory is short. I have thought about random files but I was not sure if anyone would use them, perhaps I am wrong there also.

An another subject, has anyone tested the editing and programmable keys functionality? Any bugs or issues?

Geoff,

I have options set for the function keys and is working fine. No problems found either with editing.

My only problem this afternoon is trying to input a hex variable using INPUT.
I am working on a solution with code but it's not elegant, it would be good if VAL could return a Dec value from &HFF. (Or if someone can point out another way)

Cheers,
Anthony.

Hi ajkw,

if you input a string with the INPUT command, and then convert is using VAL, like this:


INPUT A$
A = VAL("&H"+A$)



This should work, I think. I've used that way before on other computers and different BASIC dialects.

Or if that doesn't work, i posted a much less elegant code snippet on 30 July at the end of a thread called Coding Tips.

Ahh,

oops, it doesn't, but it *should*.

Geoff, why doesn't that syntax work?

If I type PRINT &H55 I get 85: REM CORRECT!
If I type B$="55":PRINT VAL(B$) I get 55 as expected.
If I type B$="&H55":PRINT VAL(B$) I get 0 !!

The short answer is because I did not think to put it in !
But it is easy enough to add, and I will.

Thanks Gentlemen,
Whilst you have been posting I was having a look at James' code.

Look forward to being able to use VAL.

Cheers,
Anthony.

geoff would it be too much trouble to have six of the function keys pre designated into the hex as a constant...run..load..print..save ..list..files... regards sparkey...generally these functions would be the most popular ...this would leave six programmeable keys left maybe you could ad in a "cls..or new..as well ....regards sparkeyEdited by sparkey 2011-10-03

When not programmed the keys generate a unique code which can be used in a program. Pre programming them would prevent that.

It is much better to define them as you need to in autorun.bas.

That line is in an already loaded Basic program from SD-Card? Is a "multi-command" line?
