Re: tn5250 problem on Win32: SBA order to row 1 column 0 fails

Hi,

Testing it with a server, I got an error that does not occur with other tn5250 clients I have tried. I think the error is caused by an SBA order to row 1 column 0 in the outgoing data stream used by the server. The

IBM manual seems to say that this should work.

Here's what I find in the IBM manual:

   "The row is equal to 1 and the column address is equal to 0, followed
    by an SF field starting in row 1, column 1. Any other use of 0 in row
    or column address results in a parameter error."

Here's the relevant code in lib5250 (session.c):

static void
tn5250_session_set_buffer_address (Tn5250Session * This)
{
  int X, Y;
  int width;
  int height;
  unsigned long errorcode;

  Y = tn5250_record_get_byte (This->record);
  X = tn5250_record_get_byte (This->record);

  width = tn5250_display_width (This->display);
  height = tn5250_display_height (This->display);

  if (Y == 0 || Y > height || X == 0 || X > width)
    {
      errorcode = TN5250_NR_INVALID_ROW_COL_ADDR;
      tn5250_session_send_error (This, errorcode);
      return;
    }
