Re: Runtime input to ncl script

Hi Gibies,

I'm afraid there's no way to do this with NCL. We have a sample of this using a C program, but it's going to be a bit more complicated to do the graphics.

Try running:

   ng4ex xy13c

to see if it compiles (you need some additional X11 libraries). This command will copy "xy13c.c" to your current directory and try to compile it using "nhlcc".
Once it runs, you can click on the pop-up window with your left-mouse button to get values.

Wei Huang has developed a prototype Java/NCL interactive GUI. Maybe it can do something like this? Wei?
