Hello,
  here is a section of code I've been having trouble with,
in a program which uses curses.
(the problem is the same on SunOS 4.1.1/SPARC and OSx5.1/Pyramid 98xx,
using standard cc on both machines, ucb universe on the Pyramid -
the program works ok in att universe on the Pyramid )

The problem is, I am trying to display the array 'abroll' on the
screen, in a 6 row by 12 column format, evenly spaced.
The current behaviour is to print the first number in each column
in the correct place, and the other 5 appear around column 78 of the
same line as the first number . If I remove the commented out section 
of code, below, the program works.

 I have experimented with location and amount of
refresh(), but it seems to make no difference.
Could someone out there _please_ reduce my frustration, and
see the error that I'm missing (apart from the obvious one of
using curses in the first place :-) 

Also, I am seriously considering using termcap directly instead,
but I am not sure how to go about this, (I have RTFM, but I would
like some example code ), and would appreciate
some pointers in the right direction.

Thanks in advance,
     
  int l1,l2,abroll[12][6];

  initscr();
  crmode();
  nl();
  clear();

  for(l1=0;l1<12;l1++)
    for(l2=0;l2<6;l2++)
      {
	move(l2+6,l1*4+5);
        refresh();
        printw("%2d",abroll[l1][l2]);
	refresh();
/* when I include this commented out code, it works fine ... */
/*	move(23,1);
        refresh();
	printw(" debug : gxy(%d,%d) ",l1*4+4,l2+6);
	refresh();   */
	sleep(1);
     }
