Which isn't a single line. My usual code is:

   IF FALSE THEN
     REM Running on pre-BASIC V
   ELSE
     REM Runnning on BASIC V
   ENDIF

but, again, is not a single line.

which will give an error on pre-BASIC V. And, if it doesn't you can't
guarrantee that you're running immediately after startup.

Which generates an error, and so consequently isn't a single line.
