/*
**  GETW -- get word
**
**	This routine matches getc except that it returns words instead
**	of bytes.  There are no word boundary problems.
**
**	There is probably a more efficient implementation.
**
**	Parameters:
**		iop -- I/O pointer of input file
**
**	Returns:
**		The next word from the file.
**		EOF on end of file or error.  Note that this is a legal
**			return value also.
**
**	Side Effects:
**		file activity
**
**	Defines:
**		getw
**
**	Requires:
**		getc
**
**	Called By:
**		USER

**	Compilation Flags:
**		none
