Displays a “column ruler” momentarily above the current line
Splits the current window horizontally so that it is 72 columns wide.
This may help you avoid going over that limit (
The command C-c C-r (
fortran-column-ruler) shows a column
ruler above the current line. The comment ruler consists of two lines
of text that show you the locations of columns with special significance
in Fortran programs. Square brackets show the limits of the columns for
line numbers, and curly brackets show the limits of the columns for the
statement body. Column numbers appear above them.
Note that the column numbers count from zero, as always in SXEmacs. As a result, the numbers may not be those you are familiar with; but the actual positions in the line are standard Fortran.
The text used to display the column ruler is the value of the variable
fortran-comment-ruler. By changing this variable, you can change
For even more help, use C-c C-w (
command which splits the current window horizontally, resulting in a window 72
columns wide. When you edit in this window, you can immediately see
when a line gets too wide to be correct Fortran.
