Well, I just installed OpenCoarray and downloaded a pi/4 monte carlo code that Thomas wrote using REAL. I changed everything to use REAL(10). Compiled and executed without a problem. I also tested REAL(16), which worked although it's painfully slow due to software floating point. So, I guess I don't understand what you're asking? -- Steve
