Has anyone figured out how to automatically place a character (e.g.,
&) in the same column of selected lines? This would be really useful
for Fortran continuation lines. So far I can't see how to do it other
than spacing one by one over from the end of the text to column 73,
which is really tedious if you're updating old code with a lot of
continuation lines.
I don't see quite what you're wanting to do, but the following UNIX
filter will insert an ampersand after the 73rd character of selected
lines or of all lines in the target document if no selection is made.
You need only modify the substitution line to get what you want, I
guess:
# /usr/bin/perl
while (<>) {
s~^(.{73})(.*)~$1&$2~;
print;
}
