This was pretty common in Turbo Pascal, your program would just suddenly stop working when you added a new blank line. (It would compile, but something would usually be off in the output causing the program to fail or crash). Removing the offending line or adding a different mix of blanks/instructions would get you back to a working state again. Very frustrating.
