Execution Error

This is a fatal error that prevents IDL from compiling or running code

This issue detects when you have a compile_opt statement that has no compile options.

Here's an example of how to reproduce the error:

pro myPro
  compile_opt
  ; ^^^^^^^^^ empty compile opt

  ; ... logic

end

To fix, add any compile option to the list (preferably idl2):

pro myPro
  compile_opt idl2

  ; ... logic

end
