Yes, more or less. To use less commands:

clear all
close database all
set exclusive on

use aaa
pack
use bbb
pack
use ccc
pack
use

Note that:

1) You don't need to switch to different areas, since you only need one table at a time.

2) By using only one area, you only need to close the last table. The first table is closed when you open the second one, etc.

3) By using SET EXCLUSIVE ON, you don't need to open each individual table with the EXCLUSIVE option.

Also, if you have all the tables in the same directory (folder), you can use adir() to get a list of tables, more or less like this:

set exclusive on
for i = 1 to adir(laTableList, "*.dbf")
  use (laTableList(i, 1))
  pack
next
use

adir() creates an array of files; the first column of this array contains the file names.

Use the Windows Task Scheduler. http://www.iopus.com/guides/winscheduler.htm shows you an example. A Google search for "Windows Task Scheduler" should gives you additional examples.
