The simple point first: the "append" command does what 
/File/Append data does.

As for clearing data, I've put some experimental things is place.

For the script equivalent of "/File/Clear data set" I've added a 
"clear" argument to the "dataset" command.  That is, you say

  dataset clear

But this has a "preserve" option:

  dataset clear --preserve

which has the effect that existing named matrices are not 
destroyed.

Similarly, the commands "open" and "nulldata" have a --preserve 
option: clear most stuff out, but keep matrices.

At present the --preserve option does not have a GUI counterpart.

Allin.
