Write your reply.

assistant: So I would put the new when I declare it?
//Excluding structure definition for space
int main(void) {
   maptile *local_map = new maptile[9][21];
}
or could I just put:
   maptile new local_map[9][21];
I have the program working with the memory now...just gets mixed up
sometimes, I am wondering if that is because I only use the 64k stack
space...Maybe this way it will keep it straight.
Thanks alot for the help!  Since I am writing this message, might as well
include this too, Turbo C++ doesn't come with Turbo Assembler does it?  Does
it come with an Assembler at all?  I have a book on Serial communications in
C/C++ that has assembly code, but my version of Turbo C++ doesn't have it.
If it should, then I got ripped, since I bought it at a software
store...Egghead I believe.
Well, thanks for the input.

[ problem situation for keeping a binary tree balanced: ]
This is still fairly easy to handle as a rule.  Load the data into
memory in an array, then create your binary tree out of the data
recursively.  For the moment I'll assume a fixed record size in the
array:
template <class T>
struct node {
    node *left;
    node *right;
    T *data;
    node(node *left, node *right, T *data);
};
template <class T>
class dictionary {
    node<T> *root;
    long entries;
    T *data;
    void create(T *start, long number) {
        create(start, number, root);
	}
    create(dict_entry *start, long number, dict_entry &*root) {
        // create a node for the middle item.
        root = new node(NULL, NULL, start + number / 2);
        // put any items below the middle in the left subtree
        if ( number / 2 > 0 )
            create(start, number / 2, &(*root)->left);
        // put any items above the middle in the right subtree
        if ( number / 2 < number )
            create(start+number/2, &(*root)->right);
    }
public:
    dictionary(ifstream &str) : root(0) {
        str.read(static_cast<char *>(&entries), sizeof(entries));
        data = new dict_entry[entries];
        str.read(static_cast<char *>data, entries * sizeof(*data));
        create(data, entries);
    }
};
As with many recursive solutions, this is almost deceptively simple.
Due to division on integers truncating instead of rounding, this will
create trees that tend to be skewed slightly to the right, but not
drastically so.

Unless you've got a very unusual graphics card, this isn't going to get
you back to text mode...
This still isn't going to be any kind of speed champ with most
compilers.  The problem is that you're re-creating the pointer to memory
again at each iteration of the loop.  With most compilers, the following
is likely to be faster:
void GraphicsScreen::Box(int x1, int y1, int x2, int y2, unsigned char col) {
    int x, y;
    char _far *spot = (char far *)MK_FP(0xa000, y2*320 + x2);
    int offset = 320 - (y2 - y1);
    for ( y = y2 - y1; y; y--) {
        for ( x = x2 - x1; x; x--)
            *spot-- = col;
        spot -= offset;
    }
}
This also draws from bottom to top, which is often faster than top to
bottom.  Even if it doesn't make any difference in accessing video
memory, it avoids comparisons each time through the loops.
You didn't call `new' to create gs - you should NOT call `delete' to
destroy it.  This was likely what was causing your GPF.
Most likely you also want a pause between putting stuff on the screen
and going back to text mode:
int main(void) {
    GraphicsScreen gs;
    gs.Box(100, 100, 200, 200, 0x13);
    gs.PutPixel(150, 150, 0x2f);
    getch();
}
For the sake of clarity, I'll post the complete, working program in the
next message.

    Jerry.

    There is nothing difficult. Borland Int. creates his apps. very nice for

with examples. It's good, but at first steps...
    Well, there is more libruares in TC++ against C++ of other companies. So,
you already have graphics libruary, libruary for working in text mode. But
functions in this libs are slow and in most time unuseble. So, I use always
my own functions for output to displaying device.
    Another bad factor in using this additional functions - uncompatibles.
So, if you want to compile your program with WATCOM compiler, you should
re-write additional functions (such us "clrscr()"). And you can forget dream
to compile under WATCOM program wich uses BGI (Borland Graphics Interface).
    But under Windows many OOP classes may be wonderful. For example, it is
ObjectWindows (like Turbo Vision) Libruary, which helps to develope interface
simply. No flexiblity, but you don't need it in this case...

If you create a project with appwizard defaults (incremental link & build),

2) Place construction-sensitive object in the global space. Eg.
   CString foo("Bar");
3) Build rormal and execute.
Doing that I get az "illegal instruction" crash during the initialisation.
The table that holds addresses for ctors needed to call is not handled
properly on that circumstances, and the program will jumt to random address
instead of the ctor for CString.
Doing a "rebuild all" removes the problem.

assistant: really
Both.
With limitations.  Some can be significant, it depends on the situation.
(Sort of like with the old UCSD Pascal.  It was portable just like Java,
but you couldn't really do anything serious with it, and it was very
slow. Java is NOT a new idea. They just repacked it with a new label and
is being sold to a lot of people who don't know any better.)
Hopefully.  Or better yet, like Forth, Lisp, etc.
and
The programming language is fairly irrelevant.  It's more important
about the specs the program was written to, and all the old databases.
