David, thank you! It helps me out soon!
But I still wondered why there is not an such usually used
function inherent in IDL, instead it depends on the 3rd-party tools.
Additionally, David, I have another personal question. Why would you
like to develop open source software on a commercial platform (such as
IDL) ? Actually, there are many free softwares you can rely on,
such as Python, Scilab, and et.al..
[Indeed, I don't have and prejudice against IDL.]
Best,
Nico
