Please look in your textbook for the rules regarding Fortran fixed-form source. They are quite specific that the statement field starts in column 7, and the continuation indicator (your example uses &) must be in column 6. Many of your source lines do not follow those rules.

Please also read about free-form source, which is the ONLY thing you should be using in new development. Admittedly, you are using code you got from someone else, but they should know better. You can make this work with fixed-form if you follow the column rules. (Don't go past column 72 in any line, also.)

One last thing - these errors occurred when you tried to compile (build) the program, not run it.
