Re: Re: Wrapping Strings

thanks for the help! I am writing this to do a cgi and am having problems embedding the html into your code.


print STDOUT join ("font face=\"courier\"><p>" substr ($strings[$_], $
+x, $line_length), $/ for (0..2)) "</font><p>";

Can you see where my syntax is bad?? thanks again

hi If you are doing cgi then I suggest that you check out Ovid's "Web Programming Using Perl" Course which is a pretty good intro to CGI programming. Might I also point you to Bioperl which is a bioinformatics perl site where lots of common sequence manipulations etc. have already been solved. A.A.	[reply]

You might not have noticed, but the `print` command can take a list of things to print, which means that `join()` is really not required. The syntax error is that after your first string where you establish the font, you don't use the period to concatenate, or a comma to make a proper list. `foreach (0..2) { print '<font face="courier"><p>', substr($strings[$_], $x, $line_length), '</p></font>', $/; }` [download] I moved the `for`-loop into a more obvious location. Before you were losing it in the print statement. I've also take then liberty of opening your `<FONT>` tag properly, as well as using single quotes to avoid having to escape the quotation marks in your HTML. As another note, `print` sends to STDOUT by default, so there's no real need to specify that.	[reply] [d/l]
