Fortran Installation

[Lou Umscheid]

Another concern that just occurred to me is the installation of a BASIC 
Cygwin installation. Does that mean that the files that I have 
transferred from the old system and tuning that I have already done will 
have to be redone? Can I do your cygstart step on my current 
configuration? Again many thanks for your help. Lou
