here an example for my wish "user defined stuctures"

If you can confine your structures to contain only variables of one data type ( words ), you could use an array. By naming the element indexes as constants, you can achieve almost exactly the same result.

But yes, now that the bigger AVRs have plenty of SRAM memory, it could be useful to implement the Basic TYPE construction. One issue still is that its not obvious to the programmer how much memory is being used, and its very easy to create structures which use far more memory than some AVRs have. At least with arrays, a glance at the relevant DIM statement shows how much memory is allocated.

Not sure about nested structures like you want, that is another level of complexity.

when you type :

Type Test
Aa As Byte
Bb As Word
End Type

and look at the code explorer you know this wish is already on the todo list. when it is actually released for the compiler i can not tell. a matter of priorities.

I feel stupid. What is a struct? and whats its importance?

I see it ALL the time in C, and I am not a C developer so it eludes me.

The equivalent basic term is a TYPE. Ie a collection of lower order variables of different sorts, but treated together into one variable name. Useful, but can be done with arrays and overlays in Bascom.

so TYPE is just a pointer in memory to those variable locations defined under it?

Yes, you could look at it like that. The advantage is in the way you reference any of the components. See a full description of TYPE in Visual Basic ( or soon in Bascom ! )

I never knew it even existed, and ive wrote alot of stuff. But the stuff I write have all been control systems related with no games, etc.. So maybe I never needed it for anything.

@Mark
any news with this feature?

it's frustrating

as Mark told you: It's a matter of time and it will be there if you can see it it newer version...

you can't speed up the process by asking multible times...

clear now?

German language:
Mark macht wirklich alles Menschen mögliche und bemüht sich sehr.
Wenn er sagt, dass es kommt, dann kommt es auch.
Weil er aber an den neuen Programmieralgos hängt, was einfach wichtiger ist, dauert es eben noch.
Es ist ohnehin eine kostenlose Leistung!
