Hi,

I've finally got round to programming my Colour Maximite 2 (and making lots of mistakes in the process!)

Back in the day when I was learning to program in BBC Basic, I found the list of errors and what they meant helpful. I'm not saying the errors aren't good in MMBasic (quite the opposite), but sometimes coding and making an error its helpful to be directed to a possible fix.

I've seen a few people on the forums mention compiling a list, but I've not been able to find anything. I was thinking of something like:

Error: Expected A Number
Description: An attempt to assign a string to an Integer / Float variable.
Resolution: Use VAL to convert the string

Example:

> DIM day AS Integer
> day = LEFT$(date$,2)
> PRINT day

Error: Expected a number

Correct Syntax:

> DIM day AS Integer
> day = VAL(LEFT$(date$,2))
> PRINT day

12

Do people think this would be valuable? I'd be happy to make a start pulling a list together that could be extended by others.

I think that this is an excellent idea. This would make a great troubleshooting resource.

There are 1467 (this is not a typo) calls to the error routine in the CMM2 firmware - good luck

That's calls, but does that mean there are 1467 actual different error messages/codes? ie: do like a group of 10 different places all trigger the same error message? If so that really only 1 error code for those 10 calls... ?

But yeah, a good table of the various errors would be good to have (I've run a few that made me scratch my head to understand what it meant for a bit...)

No: but there is no simple way of finding out how many. Someone could possibly download the firmware and then use grep or something similar to find out

Does the error routine have some sort of if/then or case/select/switch logic for handling and producing the output? If so we could at least get a dump of that section of the code to get the count of unique error outputs. Wouldn't give us all the 1467 potential reasons for those error outputs, but would be a start...

No: it is just a call with a string and optional substitution fields

if(!isnamestart(*p)) error("Invalid character: @", (int)(*p));

Ah, gotcha... Yeah, would have to be a Grep type search to produce the list then... Poop.
