Oh, didn't notice that.

So was I. I think this is a 'feature' of Fortran 77; Fortran 90 has module
files that do this.

I really don't know *why* anyone would still want to write in a language that
lacks e.g. dynamic memory allocation and has an 8 character length limit in
function names and so on. qrupdate seems to have been written in 2008-2009!!!

(Not to mention that modern Fortran compilers often have lacking F77
capabilities..)
