Hi all,

i'm working on a disassembler for the M68K and
have the  following situation.

	public class m68kDisassembler
	{
		#region MC68K Mnemonic Strings
		static string[] m68kMnemonics =
{"abcd","add.b","add.w","add.l", etc. etc ...
		#endregion

		class OPCODE_NODE
		{
		  ushort	op_mask;
		  ushort	op_code;
		  OPCODETYPE	opctype;
		  CPUTYPE	cpubits;
		  ADDRMODE	addrm;
		};
	}

now i want to make an array of OPCODE_NODEs and fill them with the 
correct data. I'm trying this.

	private static OPCODE_NODE[] Group_0x0 = {
		 {0xffff, 0x003C, m_ORI, opct_CCR, ALL, IMPLIED},
		 here the next initialization
		and the next
		.
		.
OPCODETYPE,CPUTYPE, and ADDRMODE are enums that are within the code, so
all symbols are existion.

This is the way i'm doing with a c++ compiler but somehow i don't get it
how to make it in cs.

Any suggestions ?

Regards,
Robert

You should probably be using structs instead of classes here.

Thanks a lot!, the struct hint and the way you pointed me works.

The struct constructor had to be done _public_. I got a an error while 
it wasn't.

This works also be only with this line:
	...
new OPCODE_NODE (0xffff, 0x003C, MNEMONIC.ORI, OPCODETYPE.CCR,
CPUTYPE.ALL, ADDRMODE.IMPLIED),

I have to use the enum Name. Somehow there is a namespace problem if i 
don't use the enum name.

My code looks like this.

----------->
namespace madis
{
		#region MC68K Enumerations

		public enum M68KType {M68000 = 0};
		public enum MNEMONIC { ABCD=0,
	ADDB,		ADDW, 	ADDL,
	ADDAW, 	ADDAL,
	.
	ORI,
	.
	public class m68kDisassembler
	{
	.
	.
	.
		private static OPCODE_NODE[] Group_0x0 = {
			new OPCODE_NODE (0xffff, 0x003C, MNEMONIC.ORI, OPCODETYPE.CCR, 
CPUTYPE.ALL, ADDRMODE.IMPLIED),
	.
	.
	.

Robert,

Is this going to be an open source project? I wrote some open source
IDE's for embedded processors using Delphi, and I'd like to do some of
this with C#.

I cannot say this at this moment since i've just started to learn C# and 
.NET, but if all goes alright I also plan to do a dubugger out of this 
for several binary formats and architectures not only the m68k.

As far as i've seen C# is very suitable to do a IDE. :-) Good luck!
