Paul,
The program in my previous post will help you. Just store it in the directory with your 2 programs, I usually name it SDBACK. Every time you want to back up your programs, just run SDBACK directly from the VARS menu, and it will do the job.
If your programs are in { HOME MYPROGS MYDIR }, they will be stored in the SD card in /MYPROGS/MYDIR, each program in a separate file, named exactly like in the calculator.
For this to work well, you need to avoid using strange characters when naming your programs (and directories) in the calculator, like using the arrow or the sigma letter, etc. You can only use characters that will be accepted as a file name in a FAT filesystem, so stick to plain ASCII.

Hope it helps.
