Re: [MacPerl] Starting Off [was ongoing support of CFM68K]

Given your 3 projects:

>>2) analyse the popularity of songs on a site with 50 RealAudios on it,
>>currently getting 1100 ram downloads a day,
>>3) extract multiple search engine responses for offline browsing (there's

and your context:

I'd work through the following:

1. Write a script that takes the string "name=jim&age=35" typed on the
keyboard and print it back to the screen in the line "What was typed is:
name=jim&age=35"

2. Write a script that takes the string "name=jim&age=35" typed on the
keyboard and splits it up and puts it into and array which has two
elements, being "name=jim", and "age=35", and print each element to the
screen with each element being on a seperate line.

3. Write a script that takes the string "name=jim&age=35" typed on the
keyboard and print it to a file.

4. Write a script that opens the file in 3 above and prints the string
"name=jim&age=42" [note age has changed] by first reading the line from the
file.

5. Get a message which you created to print on your screen by trying to
open a file that you know dosen't exist.

6. Write a script that uses a here document to print the following to your
screen as it is [that is there will be text on five lines]:
A person could get
RSI without here documents, a little
bit here, a little bit there and
no hassle with newlines all
the time.

7. Put this script on your webserver, and get it to run by clicking a
submit button in an html form

#!/usr/bin/perl
use CGI::Carp 'fatalsToBrowser';

# the old html on the way back to client that called the script line
print "Content-type: text/html\n\n";

# what you are sending back
print<<'HTML';
<html>
<head><title>That Was Easy</title>
<Body bgcolor="white">
Check this out.
</body>
</html>
HTML

8. Create a html form that takes two bits of input from a user and sends
that input to a cgi script which you've written and placed on your
webserver. Make the cgi script send back to your browser some html that
simply says: "The string that is the input is: ..........."
$ENV{'QUERY_STRING'} when the script is called will contain the input string.

9. Do the same as you've done in 8 using the module called CGI.pm

Hope this helps ... sorry about delay.

Cheers ... John
