winfldc (ul_pccns)

	in_field.i4.v = winfldc(window_id.i2.r, row.i4.v, left_column.i4.v,
				num_columns.i4.v)

	This routine will return a value of TRUE if the TV cursor was in
	a specified field in the indicated window the last time the
	window_intype routine was called.  The field is specified by
	a row inside the window ("row"), a starting column inside the window
	("left_column"), and a number of columns ("num_columns").  The top
	left character inside the window border is row 1, column 1.  The top
	left character of a borderless window is row 0, column 0.

	window_id	window ID
	row		row of field
	left_column	left column of field
	num_columns	number of columns in field

	This function returns status values as follows:

	TRUE			interrupt was in the window field
	FALSE			interrupt was not in the window field
