What is the expected output? What do you see instead?
The lexer definition for ID (line 44) should be extended in Bdpl.g so that
'_' is allowed to be the first character in an identifier.

Please use labels and text to provide additional information.

The grammar for initializer list is wrong. There should be any number 
children allowed. 

 DataNodeAbstract should store endianess etc

input : 
struct outer
{
    byte size;
    struct outer
    {
        byte[size/2] n_bytes;
    }[*] b;
}[*] c;

file "x:/test/file_test.dat" inp_file;
read(inp_file,c);
print(c[0].b);


output :
ARRAY of struct:outer
[
]

The DataNodeAbstract interface should have a function to set the
initializer list for any new data node that is created.

What is the expected output? What do you see instead?
The problem is in line 163 in the grammar for 'array'. The size field
allows range_list. This is not correct. range-list does not mean anything
in an array declaration. This should be changed to expr.

Please use labels and text to provide additional information.

struct outer
{
    byte[*] first;
    byte[*] second;
}b;

file "x:/test/file_test.dat" inp_file;
read(inp_file,b.second);
print(b);

doesn't work !

well , but setting fieldsize 0 may not give unexpected results after all :-)

The DataNodeAbstract interface requires that fieldsize be an integer.
However, field size can be an expression. That means the argument to
set_fieldsize should be an AST.

The BDPL parser allows break and continue statements anywhere in the code.
This is incorrect. Break and continue should only be permitted inside the
body of a loop.

The solution could be that break and continue are not normal statements.
The options for the stmt in a for syntax could be either a normal stmt,
normal stmt block or break or continue or statement block with break/continue.

need class diagrams automatically generated as a part of javadoc .

ALL test programs should have extension bdpl.
