Sorry Andrew,

I mis-read your post and I can't do that test right now.

All is forgiven

Trust me it is a dinky little "0C" and CHR$(96) is still "`".

This isn't a manual issue, it is a font issue. I'll fix the font to be compatible with the others in the next beta

Hi Peter,
Are you able to preserve the "0C" somewhere - it can be useful?
Cheers,

Andrew

Sorry, I'm sure the manual is constantly under revision but:

Page 10 says:

Quote There are 12 pins marked as supporting analog I/O

As there is no SETPIN AOUT command, should that read:

Quote There are 12 pins marked as supporting analog input

And the descriptions for the relevant pins change to Analog IN?

Page 36 still says:

Quote While playing in this background mode the Colour Micromite 2 can edit programs

Page 48 still says:

Quote NOIT will invert the logical value on the right.

Perhaps the description for the ADC command on page 53 could be changed to:

Quote The ADC functionality can capture up to 3 channels of analog data in the background at up to 500KHz per channel with user selectable triggering

p44 in the description of the CMM1 sprite format:

"The following example shows a red mouse pointer. The first line of the file holds the parameters for the sprite
(ie, the width, starting sprite number and the width in that order)."

I don't think it does

I may be wrong but I believe the parameters in the first line are (dimension or height), (number of sprites in file) and optionally (width).

Tom

should read

Quote The first line of the file holds the parameters for the sprite
(ie, the width, starting sprite number and the height in that order)."

sscanf((char *)buff, "%d,%d, %d", &width, &number, &height);

sscanf((char *)buff, "%d,%d, %d", &width, &number, &height);

Then how does MMBasic know the number of sprites in the file? According to the MMBasic 4.5 manual:

The first non-comment line in the file must be the specifications for the sprite file as follows:
dimension, number
Where 'dimension' is the height and width of the sprites in pixels. At this time it must be the number 16.
'number' is the number of sprites in the file and is limited only by the amount of free memory available.

Did the format change after the CMM1 but before the CMM2 ?

You are correct should read

(ie, the width, number of sprites, and the height in that order)."

Not an error but maybe the manual could include some information from this post it may help prevent some people from being caught out.

Thanks guys, I have made the changes.

Peter; at some point we will need to merge these and your changes to the manual.

Using ALL as the 'type' argument to the DIR$ function is undocumented.

And (though I believe you already know this) VOL is not supported as the 'type' argument.

There is another funny one: "optimised" that takes you into the MATH section.

Hi Geoff, All,

Minor typo in OPTION F11 string$ (User Manual 5.05.04)

The example quotes OPTION F12 �RUN �+chr$(34)+�myprog� +chr$(34)+chr$(13)+chr$(10)

i.e F12 rather than F11

Kind Regards

Mick

This would be a better thread for a manual thing I mentioned elsewhere:

capsikin said
I've noticed that the second argument to MODE can be left off, this should go in the manual if it's officially supported: "MODE r, [bits [, bg [, int]]]" with the extra square brackets instead of "MODE r, bits [, bg [, int]]". Is there a default colour depth?

And I also saw this one in another thread, which looks like manual errata:

fiziwig said Play Sound 1,B,N,200 ' starts the sound as expected, but

Play Sound 1,B,O � � ' gives syntax error.

The manual says (pp74) "frequency...must be specified except when type is O."

But to actually work the frequency must be specified with type O:

Play Sound 1,B,O,1

In the manual entry for the OPEN command on p73:

Quote See also OPTION ERROR and MM.ERRNO for error handling.

should be

The function HEX$ does not appear in the bookmark list of functions.

==================

I realize this is the way it's been done to date in MMBasic manuals, but must commands and functions be in separate lists? Yes, I know, commands do something and functions return something so they operate quite differently. But I often find it awkward when I have to flip back and forth between sections. And some commands and functions have the same name, which might be even more helpful if they were together.

Is the user manual available as a (libre)office document? Maybe I could play around with it and see what a merged command/function list would be like.

Visit Vegipete's *Mite Library for cool programs.
