AW: Wierd Perl syntax ($#$dlr) explanation, please!
Ok, now I see, check the following code: use strict; my @a = (3, 2, 1); my $max_index_of_a = $#a; print max index of a is $max_index_of_a\n; my $ref = [EMAIL PROTECTED]; # a reference my $max_index_of_ref = $#$ref; print max index of ref to a is $max_index_of_ref\n; Bye, Dietmar -Ursprüngliche Nachricht- Von: Kevin Hill [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 21.

I read that in the manual but it didn't make sense to me in the way that this was being used. There is a loop and, within it, the following: next if ($#$dlr == -1); How would the awk-stuff below fit with this code above? Ta. K.

From perlvar: $# The output format for printed numbers. This variable is a half-hearted attempt to emulate awk's OFMT variable. There are times, however, when awk and Perl have differing notions of what counts as numeric. The initial value is ``%.ng'', where n is the value of the macro DBL_DIG from your system's float.h. This is different from awk's default OFMT setting of ``%.6g'', so you need to set $# explicitly to get awk's value. (Mnemonic: # is the number sign.) Use of $# is deprecated. So $#$dlr is $# followed by $dlr. Dietmar -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von Kevin Hill Gesendet: Freitag, 21.

Guys, Just found this in some of our legacy Perl code - any idea what it does? $dlr is a scalar, containing the name of a dealer. $#$dlr Thanks for any help that can be given. Kev.

AW: Storing a 32-bit integer in 4 bytes
You're writing the string 31554399 to the file. Use something like print WRITE pack(I, $num); See perldoc -f pack Dietmar -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von Sisyphus Gesendet: Mittwoch, 20. Februar 2002 09:51 An: [EMAIL PROTECTED] Betreff: Storing a 32-bit integer in 4 bytes Hi, Can a 32 bit integer be written to a file in such a way that it is stored in only 4 bytes ? I thought that binmoding the filehandle might do this - but I'm finding that a number such as 31554399 is consuming 8 bytes (one byte for each digit), irrespective of whether the filehandle has been binmoded or not. my $num = 31554399; open (WRITE, test_file) or die Can't open WRITE: $!; binmode WRITE; # or not print WRITE $num; close (WRITE) or die Can't close WRITE: $!; Cheers, Rob ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
AW: The Perl Journal is dead :(
From http://news.perl.com The State of The Perl Journal [Links] EarthWeb bought The Perl Journal back in May 1999, and now EarthWeb has sold its web sites and newsletters to Internet.com. It is not clear how TPJ will be affected. Jon Orwant, editor of TPJ, sent out some email telling us what's going on: TPJ is apparently still owned by EarthWeb, issue #20 is done but waiting to be printed, and the future of TPJ is uncertain. Read also the Email from Jon Orwant at http://use.perl.org/article.pl?sid=01/01/03/0044235 Dietmar -Ursprungliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von Jose Quesada Gesendet: Mittwoch, 17.

It seems that TPJ has died, definitively. Somebody knows if there are any mirrors keeping the invaluable articles?
