Hi,
how can I use a module that is located in the same directory as my .pl file?
I'm searching for an equivalent to the C++ #include "headerfile.h" directive,
which includes a header located in the current pwd.
Thanks

You need no changes at all to receive the input. Getting the input however

Sorry, nope. The thing is that shell scripts are essentially shell commands
for control, and external commands for everything else.
OTOH, manually rewriting a shell script in Perl is going to give you lots of
experience in Perl. 8-)
My best advice: take a deep breath and dive in.

I suppose I could have a call like:

Any suggestions?

I'm working on a bit of code to update a serial LCD display. The display is
4 lines by 40 characters, and each character can be addressed individually.
First, the pseudocode I have is:

Thanks a lot! This is just what I was looking for in your first example.
(The second example won't do me as much good, as I need to consider
characters that haven't changed inside of a string of characters that
have--but it's still a good reference.)
Thanks again,

The 'exit' command should work just like it does in the shell: 'exit 9;' for

Here's a quick way:
perl -e '$var="abdaatela"; print ((scalar grep /a/,(split /(.)/,$var)),"\n");'
grep returns the number of matches in a scalar context, and the split breaks
the string up into separate elements. The parens in the split return the
item split on (otherwise it would throw away each

In addition to the suggestions already given, you could sort your array, and
then look at the middle and cut it in half (potentially several times). I
forget the name for this technique, though...
For example, you have 1000 elements, sorted. You compare your number to the
500th element. If it's hi

This is more of a Unix trick than Perl, but worth mentioning (I guess):
An(other) easy way to check for normally unprintable characters is to "send
your cat to the vet". cat -vet weatherbug.pl
-v show most non-printing characters
-e show en
Actually, while we're on the subject: can anyone *really* explain the
difference between the two, or perhaps more importantly, when someone would
want to use 'our' over 'my'? I've read the docs, but they're not sinking in.
TIA,

Does anyone know of a pronunciation guide for the special variables and such
in Perl? I came up empty on Google. I've been learning Perl by reading and
doing, but I haven't talked to anyone face-to-face, so I'm not sure, for

And we (I, anyway) thank you. I got a good laugh out of that today when I
told my class that's what it was called--"no, really, that's it's name..."

Just a quick tip, which the docs mention that 'exists' and 'defined' will
let you know if a particular element of a hash exists, or is defined, they
work on arrays just as well.
(I didn't know that, but a student today asked, so I tried it out.)

Is there any (quick and easy) way to get a reverse range, like (10..1),
rather than a standard (1..10)? The catch is to *not* use 'reverse'.
I'm teaching Sun's perl course this week (DTP-250), and we were talking
about working on arrays. The book had an exercise that had the student

*Vey* cool examples--especially the 'map' in the first one.
Thanks!

So...does anyone know a way to tell if a particular character will be
printable for a particular terminal type (so I can substitute it if I
can't)?
