title: IDL undefined procedure
body: <p>I'm using IDL 8.3 on Mac 10.9.3</p>
  
  <p>I am running a script that calls in a procedure. The procedure I am calling in is contained in a directory that I included in IDL's path (I did this by going under IDL->preferences->IDL->paths and adding the directory). However, when I attempt to run the script, I get the error message: "% Attempt to call undefined procedure/function: 'procedure.pro'. % Execution halted at: $MAIN$". The weird thing is is that it still lists all the syntax errors in the procedure that is supposedly 'undefined'. Also, when I type the procedure.pro name into the IDL prompt, it lights up teal/blue color (meaning it recognizes the procedure).</p>
  
  <p>I tried making a very simple simple.pro, put it into the same directory I mentioned before, typed it into the IDL prompt (it turned teal/blue), and it ran perfectly with no errors.</p>
  
  <p>I am unsure why the procedure.pro file is 'undefined' since it is contained it its path, and I proved with simple.pro that .pro files in this path will run correctly.</p>
