Basic unix shell commands (pwd, ls, cd etc) can be
issued from within ASAP. This allows the user to do things like look
at files in the current directory. The shell command ``cd''
works within ASAP, allowing the user to change between data
directories. Unix programs cannot be run this way, but the shell
escape ``
'' can be used to run arbitrary programs. E.g.
ASAP> pwd ASAP> ls ASAP> ! mozilla&
