Well, z/Architecture still supports the S/360 floating point operations, and some additional HFP (hexadecimal floating point) instructions. z/Architecture also has full support for IEEE binary floating point in its BFP instructions, with no HALVE instruction. I presume the descendants of the S/360 and S/370 compilers support HFP, and the newer compilers, descendents of gcc, support BFP. The machines are out there, but it much smaller numbers than IA32 machines. -- glen

Point taken. Do they have f90+ compilers? Just asking. :-) -- Cheers! Dan Nagle

Just asking. :-) Jim Xia should know. Also, Fortran, of all languages, should realise that what goes around comes around, and it is quite likely that the current approaches will change to something more like earlier systems at at least one point in the next 50 years :-) Regards, Nick Maclaren. |
