Launching Data Files (AGAIN)

[johnmac@fawlty.towers.oz.au (John MacLean)]

I previously asked for 8 bit program launchers that can be set up to
automatically open a data file on launch.
[eg: You can select a BAS type file and it automatically starts up
BASIC.SYSTEM which runs the program].
It has been confirmed that ProSEL can do this.

Can anyone authoritively confirm or deny this capability on any of the
following 'launchers' (I use the term lightly):

- Davex
- ECP 8
- Kix Unix
- Super Selector

Or any other 8 bit program launchers.

I really do not want to write my own, so I'd like to have a list of 8 bit
launchers which can do this...
