Conventions used in this Tutorial
The humour is non-conventional. I think. Of more importance, the text is coloured strangely in places. My intention is to aid your comprehension, not attempt beautification. The meaning of the colours:
- Sometimes you'll need to type something in on the command line. These commands will be
in green, for example :
perl changeworld.pl parm1 datafile.txt - Code that you should load into your editor and run is in blue (don't run this now, it's
just an example):
while (<DATFILE>) { printf "%2s : $_",$.; } - when functions are referred to in the text, their names are highlighted in red. For
example, later we discover an interesting function called
split.
All the code examples have been tested, and you can just cut'n'paste (brave statement). I haven't listed the output of each example. You need to run it and see for yourself. Consider this course interactive. Consider it any which way you like.
