Nope, in Davex you have to type "basic.system program.name".  You can make
an alias to stand for that, of course, or just for the basic.system part.

And there's a command (sysalias) that can create a SYS program that launched
another SYS program (such as BASIC.System) & automatically provide a prefix
and startup-pathname of your choice.

I've always intended to add a command to map from filetypes to commands,
so that you could associate any command with any filetype, but I've never
done it.  It could encapsulate several existing mechanisms, including
the launching of SYS and external-command files, and automatically prefixing
to a directory when you type its name.  (I'd need an explicit command name
for launching a SYS file and running an external command.)

It would be something like:
  map dir prefix
  map sys launch
  map p8c -x $yyyy launch
  map bas /h1/basic.system

Maybe some day.
