I find that simple CGI scripts are precisely the example *for* putting
multi-line string literals at the beginning of a file. There are
multiple styles for writing such things:
1. Put headers and trailers into separate strings. This tends to become
tedious to maintain, since you always have to find the matching
string (e.g. if you add an opening tag in the header, you have
to put the closing tag in the trailer).
2. Use interpolation (e.g. % substitution), and put the strings into
the code. This works fine for single line strings. For multi-line
strings, the HTML code tends to clutter the view of the algorithm,
whether it is indented or not. Functions should fit on a single
screen of text, and adding multiline text into functions tends
to break this requirement.
3. Use interpolation, and put the templates at the beginning. This makes
the templates easy to inspect, and makes it easy to follow the code
later in the file. It is the style I use and recommend.
Of course, it may occasionally become necessary to have a few-lines
string literally in a function; in most cases, indenting it along
with the rest of the function is fine, as HTML can stand extra spaces
with no problems.
