This program allows you to test your editors' support for DataOpen
"template mode" (selected by unsafe=-2). This has been implemented by
!Edit and !SrcEdit since RISC OS 2.00 and by all applicable Cerilica
programs since whenever it was I rediscovered it.

Editors should load the data and then present it as a brand new file,
retaining only the leafname (definitely NOT the whole pathname). The
file should start "unmodified" just as a blank file does.

Paint, Draw and Maestro did not ship with support for template mode,
and it was never documented. That the Filer has no mechanism for
launching a file in this way also did not help. It is most useful for
wizards (that present a range of 'blank' documents) and anything that
needs to launch a temporary file, although it is also the ideal way
to open a help file (as this program does from its iconbar menu).

Also note that though the program will try to run an editor if none
accepts the DataOpen, results will vary by filetype as the ability to
run an editor by filetype does not really exist in RISC OS, and the
Alias$@RunTypes are not always useful without a filename, sadly (if
this is true of yours, please consider changing your app so that it
can be run without a filename).
