Funny behavior under TURBO compiler

[Anonymous NNTP Posting]

Hi Netters,

I am unable to understand the behavior of following program compiled under TURBO C++ compiler. This program prints numbers 1-12. 

When "TB2 tbl" declaration is local to main() (as shown) the program works fine and the results are printed as :
1 2 3 4 5 6 7 8 9 10 11 12

If I make "TB2 tbl" a global variable the results are:
10 11 12 10 11 12 10 11 12 10 11 12

What's wrong , I couldn't figure out...

Anyone has clues..

Thanx,

		*((*tbl[i])[j]) = k++;

	for (i = 0; i < 4; i++)

			printf("%d ", *((*tbl[i])[j]));
