Hi all. I have a function in the following format:


;start of the function

function hopperbub16,num,maxframes,polyd=polyd,seed=seed,gravity=gravity, $
f0=f0,dtuser=dtuser,angle=angle,width=width,mov=mov, $
xrange=xrange,yrange=yrange, $
startbub=startbub,useplot=useplot,jamstate=jamstate,jamstring=jamstring, $
ampx=ampx,freqx=freqx, ampy=ampy,freqy=freqy,overflowmax=overflowmax, $
narrow=narrow,noforce=noforce,_extra=eee


[function body]
.
.
.
.
.
.
.
.

return,result
end

;end of the function

However, it does not give any output when I call it in the IDL console like this:

result=hopperbub16(300,2500,seed=seed,gr=0.1,wi=8.0,ov=1.0, mo=mov,yr=[-20,70],nar=10.d,/nof,/noo,/us)

I even don't know if it has been run or not. Can anyone help me to see my results? how can I put breakdown points and see if the code is running and debug it?

Thanks,

Saeed
