Basic Plotting in Running Idl Procedure

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
