Thanks. I finally found the problem. I was reading a text file and trying to add the value on line 28 to another variable. The problem was the text file was zipped in DOS and then sent to me. So, it contains an extra control code (control-M). Once I delete the control code, bc works great. Really appreciate your help.

mdraw_text_extents

mdraw_text_extents(3m17n)					 The m17n Library					 mdraw_text_extents(3m17n)

NAME

       mdraw_text_extents - Compute text pixel width.

SYNOPSIS

       int mdraw_text_extents (MFrame * frame, MText * mt, int from, int to, MDrawControl * control, MDrawMetric * overall_ink_return, MDrawMetric
       * overall_logical_return, MDrawMetric * overall_line_return)

DESCRIPTION

       Compute text pixel width. The mdraw_text_extents() function computes the width of text between from and to of M-text mt when it is drawn on
       a window of frame frame using the mdraw_text_with_control() function with the drawing control object control.

       If overall_ink_return is not NULL, this function also computes the bounding box of character ink of the M-text, and stores the results in
       the members of the structure pointed to by overall_ink_return.  If the M-text has a face specifying a surrounding box, the box is included
       in the bounding box.

       If overall_logical_return is not NULL, this function also computes the bounding box that provides minimum spacing to other graphical
       features (such as surrounding box) for the M-text, and stores the results in the members of the structure pointed to by
       overall_logical_return.

       If overall_line_return is not NULL, this function also computes the bounding box that provides minimum spacing to the other M-text drawn,
       and stores the results in the members of the structure pointed to by overall_line_return.  This is a union of overall_ink_return and
       overall_logical_return if the members min_line_ascent, min_line_descent, max_line_ascent, and max_line_descent of control are all zero.

RETURN VALUE

	   This function returns the width of the text to be drawn in the unit of pixels. If control->two_dimensional is nonzero and the text is
	   drawn in multiple physical lines, it returns the width of the widest line. If an error occurs, it returns -1 and assigns an error code
	   to the external variable merror_code.

ERRORS

	   MERROR_RANGE
