I started learning IDL a few hours ago. I have constructed the following procedure in a .pro called 'plots.pro':

PRO PLOTS num=findgen(40)*10 line=sin(num*!DtoR) plot, num, line END

It seems I should get a plot of the line as a function of num. However, I instead get the following error message:

'plots ^ % PLOTS: Incorrect number of arguments.'

I wonder if you may point me in the right direction.

The procedure name "PLOTS" is already used by a different IDL procedure. You can rename your procedure (and file name) so that it doesn't conflict with PLOTS.

PRO my_plot num=findgen(40)*10 line=sin(num*!DtoR) plot, num, line END IDL> my_plot
