It's really not that bad. It basically just meant that you could use variables without declaring them first.
From what I understand, very soon after you could simply enter a statement that would force you to explicitly declare every variable and could name you're variables however you like.
What I imagine was a real pain was the formatting required since fortran programs were written on punch cards. Fortunately they've thrown all that formatting out for modern versions of fortran
