Question: What can I do if my lines wrap around to the next line?

Answer: You have to get a feel for the location of the 72nd character position on the screen, or do a lot of counting. Once you hit column 72, you must hit the RETURN key, put some character (I like & or #) in column 6 of the next line then pick up typing where you left off. I usually stop before column 72 at some natural break point between variables:

123456789012345678901234567890123456789012345678901234567890123456789012
IF ( (X.LT.2.0.AND.Y.GT.30.0).OR.(X.GT.1000.0.AND.Y.LT.-40.))
& PRINT *,' CALCULATION IS IN TROUBLE'

Since Fortran tends to ignore blanks, the extra ones in the above 2 lines don't cause problems.
