	! This subroutine is used to enable fortran to figure out what
	! the length of a litteral string is without having to go
	! through the hassel of recounting it each time it changes.
	! Since fortran automatically appends trailing spaces to fill
	! up its fixed length strings, all trailing spaces and tabs will
	! be removed prior to counting.
