Hi,
I would like to know if anyone has a command which prints a string
that overwrites the current line. The purpose is to update users what
is going on during processing without producing a screen full of:
Processing data set 1
Processing data set 2
...
which is what PRINT,'Processing data set',i does. I think it must be
possible after hacking through rdpix.pro, but I can't figure out how
to do it :(
Ciao.

I think you understood correctly for UNIX. The
Windows way is a progress bar. :-)
Cheers,

If I understand correctly, this should do what I want:
PRO OPRINT,input
bksp = REPLICATE(8B,16)
PRINT,format='(a,$)',STRING(bksp)+input
END
IDL> FOR i = 0,100 DO OPRINT,'Number'+STRING(i)
All I should end up seeing is "Number 100". It doesn't work like
that(windows98, 5.5). I tried it with different bksp characters. Still
no. Why oh why oh why?

Thanks all for the tips/code. I try and keep my progs utterly basic so
the old format='(a,$)' will have to do for me. Thanks anyway.

Indeed. Thanks to Andrew and Peter Mason, two Aussies
who know how to have a good time, you can find an
interesting set of programs here:
http://www.dfanning.com/programs/bell.zip
These are Windows-only, since they use a Windows DLL
written by Peter.
Enjoy!
Cheers,
David
P.S. Let's just say the BEEP command just doesn't
make it anymore in the face of these offerings.

You can ring my bell any time, David.
Oops.

Ah Trouble,
You'll also find that you can't ring the terminal bell under Windows
with a print,String(7B) either. The IDL Development environment
captures
non-printable character codes and displays them as the vertical bar
character
in the Output Log. Same diff for the Backspace/Delete control code.
But if you ask Dr Fanning nicely, he'll give you a routine to ring the
bell
under Windows anyway.
Suggest you pester RSI with a Software Change Request to allow at least
a few
of the common control codes to work correctly under IDLDE.
