[moved] how to create C style bit structure

[worldcup]

I have a C style bit structure like the following

struct {
elementA : 2
elementB : 20
elementC : 7
elementD : 3
}

How can I define this structure in PPL?

Thanks

I am not sure, whether I understood your question properly, but in PPL you could define a structure like this:

struct(StructureName$,"elementA",2,"elementB",20," elementC",7,"elementD",3);

And then you could access the strucutre elements like this:

StructureName.elementA$="A";

Is this what you meant?

PPL doesn't support bit size types. The smallest you can declare is 1 byte wide.

You can do bit manipulation just like you would in C with some functions.

oh. That is pity.

I need bit structure because it can help me to assign a value to a portion of memory unit easily.

You can use bit manipulation functions like: shr, shl, asr, asl, & and |.

a$ = 0x00000001 & 0x00000010;

It is not as easy but it does work.
