Nicolas,
If you're using UNIX from a terminal then you might want to look at the
"MORE" keyword to OPENW.
As an example:
openw,unit,'/dev/tty',/get_lun,/more
for i=0,80 do printf,unit,i
if you're using Windows or the IDL IDE under UNIX then there might be an
equivalent but I doubt that '/dev/tty' means much under those
environments. It might though.
Thanks,
Allan
