WP34s and 31s: Updating the emulator while preserving all data

That is quite easy. Before installing the update, copy the file wp34s.dat from the wp34s-vers/trunk/windows/bin directory to a safe place where it won't get overwritten by the update.

After the update replace the wp34s.dat file back to it's original directory with the one you put in a safe place, then start the emulator.

It should retain the original programs and memory contents as before the update without the erased message. I have done this through many version changes with no ill effects. There is always the possibility that a new version of the emulator will partition or arrange memory differently causing an incompatibility with the saved memory file, but so-far I have not seen that happen.

Also the wp31s.dat file is stored in the wp34s-vers/branches/wp31s/windows/bin directory. Similarly save the wp31s.dat file to a safe place and restore it after the update back to its original directory.

I personally keep a "Catalog" of wp34s.dat files renamed in a safe place to describe the collection of programs they contain. That makes it easy to reload a whole family of programs with a simple file copy.

Good luck, Barry
