Hi Hal,

IMHO, your analysis is right on target.  SciTE redirects stdout (and stderr)
to a panel within it's window.  But, clearly, they didn't redirect stdin
from that panel (after writing a prompt).  So the correct solution, it seem
to me, is an enhancement of that IDE, which I can't afford to volunteer to
try.

So a work-around, as you suggest, is the path of least trouble.  The Windows
API has a function for opening an input dialog that accepts a string which
gets returned to the caller.  And Win32API provides a way to get to such a
function.  That leads me to think that it shouldn't be too difficult to
'def' a static 'wgets' method to return a string from an input dialog.

I'll look into this briefly.  If you have any off-hand comments, I'd
appreciate them.  If I can't get this going this afternoon,  I'll shelve it
in favor of using FX.

C'ya,
Richard
