64bit Salford95

but the last time we looked at this, 64 bit C# could only handle 4GB chunks.

This is still correct for .NET 3.5 (it's not bound to the language), yet the total amount of occupied memory is not limited to 4GB so this would be an acceptable limitation.

Would you mind to post an estimate whether this feature could be implemented and a rough timeframe?

Thank you.

Quoted from JohnHorspool

I cannot compile programs on the 64-bit OS

well I can only state that in 18 months of using win XP64 I have never had any problem using the 32bit Silverfrost FTN95 compiler, the program applications created work fine on 32bit or 64bit windows systems and I have even got them to run in Ubuntu Linux 64bit under 'wine', and I'm not talking of simple 'noddy' applications, but programs incorporating a standard windows interface using 'winio@' with both GDI and OpenGL graphics.

However the fact the compiler was trying to access memory above 2GB I find to be very strange behaivour, I cannot understand this.

Does a very simple program like:-

      program hello

      write(6,*)'Hello World'

      stop
      end

also fail in the same fashion?

Reply I have tried this program and I get the same error. However I tried the same program, and indeed much bigger programs on my wife's PC running 64-bit Vista and there were no problems. The 64-bit XP OS will run Fortran programs compiled on other PCs but will not compile, always giving the message 'Acess violation at address00538571 attempted to write to location 7fff0000 '

Is there soemthing in the OS setup or environment variables that could be causing this?
