Try ppm install Expect
since specifying the version does not necessarily mean that this
version is available at activestate repository.

Means that Expect 1.11 is not available through activestate repository
as I mentioned above. I don't even know if they have any version of
it, but you can check the repository, see ppm docs for repository URL.
If they don't have it, and you have VC++ compiler installed you can
download and install from CPAN.
Have you installed any modules with ppm, since this might also be a
firewall issue. If you have a firewall see ppm docs on how to bypass
it.

Hi,
I have started using perl from Activestate a short time ago, and I
have had problems when trying to install modules.
It seems like ActivePerl likes to be installed in c:\perl.
When I first installed perl in a different location, perl reported
problems with my @INC variable every time I tried to install a module.
If you haven't installed perl in this standard location, then maybe
you should try installing perl here..
-----------
Here's how I would use the package manager PPM to install your module
from the command-line:
c:>ppm
PPM interactive shell (2.1.5) - type 'help' for available commands.
PPM> search expect
Packages available from
http://ppm.ActiveState.com/cgibin/PPM/ppmserver.pl?urn:/PPMServer:
'Expect [1.10] Expect for Perl
PPM> install expect
Install package 'expect?' (y/N): y
(... blah blah ...)
PPM> quit
Quit!
-----------
Hope it works out for you!

Not quite. 'ppm install Expect-1.10.tar' would probably not work either,
because the name of the package is 'Expect' and not 'Expect-1.10.tar'.

Subject: puzzled over fork() doing something different to book example
Message-Id: <3B3746EF.9AE22D10@salford.ac.uk>
Hi,
I'm investigating fork() and have typed in an example of it from a book
("Perl Interactive 5 Course" by the Waite Group Press, p468 in case
anyone has it).
Here's the script:
#!/usr/local/bin/perl -wl
use strict;
use FileHandle;
pipe(READ, WRITE);
WRITE->autoflush();
my $pid = fork;
if($pid == 0)
{
print "\t\t\tI'm the child. Be nice to me!\n";
close WRITE;
while(<READ>)
{
print "\t\t\tParent said: $_\n";
}
}
elsif(defined $pid)
{
print "I'm the parent. Please yell at my child.\n";
close READ;
while(<>)
{
print WRITE $_;
}
}
else
{
print "couldn't fork\n\n";
}
The only things I've added differently to the book are:
use strict;
and checking for an undef return from fork()
This is perl, version 5.005_02 built for IP22-irix
According to the book (and it seems logical too), my parent process will
execute first, then the child, then the parent, then the child etc. etc.
etc. The book claims I will get something like:
I'm the parent. Please yell at my child.
I'm the child. Be nice to me!
hi there
Parent said: hi there
goodbye
Parent said: goodbye
However, the result of running this script is:
hexie 593% ./fork.pl
I'm the child. Be nice to me!
I'm the parent. Please yell at my child.
hi there
Parent said: hi there
Parent said:
goodbye
Parent said: goodbye
Parent said:
(I type in 'hi there' and 'goodbye' at the command line.)
Not only does the child half-execute first (i.e. its first print
statement only), but the parent executes then the child does what it's
supposed to do but then immediately half-executes what it's supposed to
do again.
Any ideas?

It could. The processes will be scheduled by the kernel,
but you can't say which executes when.

The child got scheduled before the parent, not unusual.
Read your OS docu to get a finer grained understanding
of the kernel scheduling.

Actually perl reads this as
hi there\n
and you write it in your pipe as
hi there\n\n
because the -l switch appends \n on print()

So you get two lines when you read the pipe
both a printed out
1. hi there\n
2. \n
Have fun,

Subject: using dbmopen()
Message-Id: <9h7h8k$c6aej$1@ID-93885.news.dfncis.de>
just a simple question. What kind of file does dbmopen() bind a hash to (BY
DEFAULT). I saw the perlfunc man page, and found that:
This binds a dbm(3), ndbm(3), sdbm(3), gdbm(3), or Berkeley DB file to a
hash.
But un-fortunately, they havent mentioned on the type of DB, file that it
binids the hash to by default. The manual also states how to tell the
dbmopen(), to use a kind of DB file, like this:
use DB_File; #tell dbmopen to use DB_File
dbmopen(....
....
dbmclose(...);
But if I remove the first line 'use DB_File', what will the program use.
