This works on my confuser (DMD 2.013, DMD 1.029):

   string[] a =3D ["Hello", "World"];
   string[][] b;

   b ~=3D a.dup;

   a[0] =3D "HAI";
   a[1] =3D "WURLD!1";

   b ~=3D a.dup;

   writefln(b); // prints [[Hello,World],[HAI,WORLD!!!1]]


Without the .dups, output is [[HAI,WORLD!!!1],[HAI,WORLD!!!1]].

Thanks -now to stick the hair back. Would never have thought of approaching it
with append . Logically I just want to put it in a firm place with a defined
index address.

Does not seem to be covered in the Tango book either.

So can you explain how you are using " string".
What are you importing to be able to use string?

This works just as well:

   string[] a =3D ["Hello", "World"];
   string[][] b;

   b.length =3D 2;

   b[0] =3D a.dup;

   a[0] =3D "HAI";
   a[1] =3D "WURLD!1";

   b[1] =3D a.dup;

   writefln(b); // prints [[Hello,World],[HAI,WORLD!!!1]]


Now, without the b.length =3D 2;, you'll get an array bounds error, of  =

course.

I'm just importing std.stdio. I think string is a compiler-defined alias=
,  =

but I
can't say whence I got the idea.

As an aside I find that with Simens help in the above I can move forward but
another problem raises its head with this array business

I am accumulating lines from a text file in my  char[][][] array. It writes the
first seven lines of an eight line file OK but on the last line it writes the
last line in the correct place but also corrupts the first lines data?

The data is fine unyil the last line
I produce the data with 

foreach (line; new LineIterator!(char) (new FileConduit ("data.csv"))){
      TableItem item = new TableItem (table, DWT.RIGHT); 
      fields = TextUtil.delimit(line,",");

Anyone have any idea why the data is corrupted?

Yes, LineIterator re-uses the same data buffer while reading the file for 
efficiency.  If you want to save the data that LineIterator gives you, use

fields = TextUtil.delmit(line.dup,",");

What this does is make a copy of the line, then split that up.  When the 
LineIterator re-uses the buffer, it won't affect your copies.

And Tango does not use 'string' as a keyword, that is Phobos only.

Hope that helps.

 ------------------------
 
 string/wstring/dstring are defined in object.d, which is implicitly imported 
 from every module.  So it might as well be defined by the compiler.  In D1, 
 they alias to char[], wchar[], and dchar[]; in D2, invariant(char)[], 
 invariant(wchar)[], and invariant(dchar)[]. 


... in Phobos.  But not in Tango.  Unless it changed in the release that 
came out yesterday or so.
