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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

To clarify ...

If you use the two paratemeter form of open, the file opens by default for reading.  You can prefix the file name as follows:

< open for read (default anyway)
> open for (over)write
>> open for append
| open a command as a receiving pipe

You cal also add to the end of the file name
| as a sending pipe

The 3 parameter form of open is clearer, and recommended if you're using a recent version of Perl and are sure you won't want to run your code on something older
