DrRacket expands your program in a mode that is relatively constrained, not allowing it certain access to the file system or allowing it to run executables or make network connections or lots of other things. This is because it starts running code (on your behalf) as soon as it opens the file in the editor and it would be bad if you accidentally opened nefarious code and it got to run right away without you looking at it.
