XPL & directories???

[Myron Gochnauer GOCH@xxxxxxxx]

I'm trying to write a small XPL program which will allow me
to choose a file from an open directory and pass the filename
only, without an extension, to a DOS program run from the
command line.

I'm having difficulty figuring out how to extract only the filename
from the line under the cursor. I thought DW might work, but it
seems to define the entire line into the S/G. My attempts with
XS have not been successful either, although I have used XS for
other purposes. (Can you save a space --- ASCI 32 --- into a
S/G with something like ≪SV401, ≫ ?? If so, will XS 'stop'
at the first instance of a space?)

Can anyone point me to a routine in some of the available XPL code
which I can copy/mimic/modify?

Thanks.
Myron
