Well, first we suggest you upgrade to 0.65.0.
It depends what `Unix' is. You may be able to tell the compiler to
use double precision, for example by -r8 -i4 on a SunPro compiler.
However, if this is really one huge routine, just put
implicit double precision (a-h, o-z)
in the declarations section, change any explicit real declarations to
double precision, and check out uses of real(), probably changing them to
dble().
