I remember wondering how on earth you could write Pascal programs without line numbers since that was the difference between running a command and entering/editing a program in the Apple ][ environment. I don't remember if Apple Pascal had what would qualify as an IDE now, although it had its own OS which made it less attractive to me.

You use a program called EDLIN that writes the line numbers for you, and even renumbers your lines automatically whenever you have to insert something in the middle of your program. It's really neat!
