For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Mechanism of foreach iteration..

Posted by kitwalker2886 (kitwalker2886), 9 June 2007
Another one on the foreach loop..
   while using the for loop..
      print $i;
   this would print a value n+1.. right??..

  but if a try to use a foreach loop in a similar way..
    foreach $i(0..n)
      print $i;

 This doesn't print any value.. its as if $i doesn't exist outside of the loop.. could u explain this please??

Yes - the second loop is empty as "n" is a bareword.  You probably meant $n  

Always use the -w flag if you see strange behavior - it'll give you the vital clues!
