can 64bit processor run both 64bit and 32bit computers?

Linux, unlike windows, is one of the first OSes to take advantage of 64bit computing. I recently found a very nicely priced Athlon 64 computer that I wanted to put Linux on. But will that mean that I won't be able to use any of my 32bit linux programs?

Thanks.

I just built a comp two weeks ago and used an AMD Sempron 64-bit CPU.
I installed Slackware -current which is a 32-bit OS, no problems.

64-bit computers have been existing for 15 years, it's just the braindead and antique ISA of the i8086 that kept them away from the PC market for so long

but if I installed a 64bit version of Fedora, Debian, etc, could I use both 32 and 64 bit progs?

Thanks,

yes, you will be able to use both.... Most of the time if you install a 64 bit distro, all of the programs will be compiled for the 64 bit chipset (like the mac versions...), but if you use a 32 bit distro, a 64 bit processor SHOULD emulate the 32 bit procesessing fine.
