For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

Three more Perl Programming examples for you ...

Use of $" to produce csv data
Efficient code with map and grep
Use of implicit loop and print (-p switch)

... All from the Topicalisation and Special Variable module of our Learning to Program in Perl course.

Puzzled by the subject line? - It's a sample of output from the third or the examples. Have a look at the code and see how.
