Not available in Maple 9 anymore: save all variables once

Greetings!

In the old versions of Maple (5 and 6, for instance), the command

save "filename.m";

saves ALL data for future use. Now, in Maple 9, it's
necessary to specify which names you want to save. This
is annoying!

I've tried to build a "save all" command by myself
combining anames('user') and the save command. Indeed,
I was able to put the whole command in a symbol with the following
code:

unassign('namesToSave'):
unassign('saveCommand'):
anames('user'):
namesToSave := [%]:
saveCommand := [`save`, ` `]:
for i from 1 to nops(namesToSave) do
   saveCommand := [op(saveCommand), namesToSave[i], ","]:
od:
saveCommand := [op(saveCommand), `"`, libFileName, `"`]:
eval_me := cat(op(saveCommand));

The problem is: I donīt know to make Maple evaluate (interpret)
the contents of the "eval_me" variable. Is there a such way?
I mean, if I have a symbol or string with a maple command, is it
possible to make Maple interpret such string and execute
the command? Does Maple operate in a meta level?

Thanks in advance, Humberto.
