thanks milez, I downloaded from that site as i surfed, I got G77 but configurations I was asked to follow has not given me an environment to create my algorithms, It might be I have not got it right. But I stumble on NAG FORTRAN youtube that has windows environment but could not get the software.k
I will get back to the site
for my department Mechanical Engineering, we do not have, what ever software I use is self sourced. How ever I'll check more sources like computer science but I will not be surprised if they give excuses.
