I just felt the comment was suiting since it must have been about when they were still used that you couldn't automate indentation.
- rbanffy 10y agoIn FORTRAN 77, it'a syntax error to put a statement before column 7
- btschaegg 10y agoInteresting! Can you explain why that is the case? Were the first 6 characters reserved for the line number or goto marks?
- rbanffy 10y agoYes. Columns 1 to 5 are for labels. Column 6, if it has any character there (usually "$"), marks a continuation from the previous line. I think the column 6 rule and line continuations were removed for FORTRAN 95.
