Since FileHandle gives you object-oriented access to the filehandle, you
can use
$flist{$key}-print(Header info\n);

print {$flist{$key}} Header info\n;
already suggested.

Re: Reading 'Little Endian - UCS-2' text to perl
Hello, I'm having difficulties reading a log file from ADMT using ordinary perl 5.8.7 open command. After opening the file (apparently in little endian format, according to my notepad++) i'm printed it and i get spaces everywhere (space between each char!). when i convert the file to UTF8 (again, manually with my notepad++) it prints out file just fine. anyone knows how to handle this encoding in perl, or how can i convert it to UTF8? If i've read perluniintro correctly, you can use an open statement like this to process the file directly: open FH, :encoding(ucs2), $filename or die Can't open $filename $!\n; -- Eric Amick Columbia, MD ___ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

There's no magic way to reset the range operator. You could add some
sort of flag, such as this (untested):
my $skip;
while (FILE)
{
if (my $tags = /TAG/ .. /\/TAG/)
{
$skip = 0 if $tags == 1; # reset flag upon seeing TAG
$skip = 1 if /PDF/;

Read the description in perlop for further details.
You could also not use the range operator at all; I'll leave the code
for that to you.

The each() function expects its argument to start with %. As perlsub

hashes are flattened when returned from a function, just as they're

In perl it does nothing. Under bash it executes perl with itself as an

The number represents the error level of the last exiting process. No

Personally I think it's just left over development code that nobody deleted.
According to the Camel Book, those lines allow Perl scripts to be run
naturally (i.e., with scriptname instead of perl scriptname) on
Unix systems that don't support #!. I don't imagine there are many of
those these days. There's no real point to it on Windows, unless your
system doesn't associate whatever extension you use on Perl scripts with
perl.exe.

No, it's a limit on the number of values rand() produces on Windows, as

perl -MConfig -e print $Config{randbits}
randbits is the number of bits in the value produced by rand(); the

There are two problems:
1) When you pass a string to use or require, Perl expects a file path,
not the :: format.
2) The arguments after the module name are not processed by require when
you pass a string.
The simplest fix is
eval require $win32ole;
If this code will be executed many times in a single run of the program,
a better way would be
$win32ole = 'Win32/OLE.pm'; # extension is required too!
require $win32ole;
Win32::OLE-import('in', 'with');
All this obviously applies to the Win32::OLE::Const as well.

Re: mystery
"use constant" defines constants something like this:
sub NAME() { return 42;}
The prototype prevents anything following a reference to the constant from being accepted as an argument. What's more, Perl will inline the function call if the return value is a constant _expression_ in most cases. The Posix module is almost entirely in XS, and clearly the part that defines the constants does not use prototypes.

If tracking the insert order is really important, it would probably be

I am reading a stream of text that may contain the two segments \\n and \" I want to define a regexp that will match up to the first of either of these.
I would suggest a slightly different approach, especially since you apparently might not have either sequence. Try
if ($str =~ /n|\\"/)
{
$mytext = substr($str, 0, $-[0]);
# do whatever with $mytext
}
The arrays @- and @+ contain the starting and ending offsets within a string of the portion successfully matched by a regular _expression_; the 0th elements refer to the whole regex, and other elements to the portions captured by parentheses.

Re: some error with the code
As you can see, perl simplified your unquoted numerical strings by dropping the leading zeros *before* stringifying them to use as hash keys. Quoting them explicitly solves the problem. Actually, Perl interprets the values with leading zeros as octal numbers; that's why 00056 became 46. I admit I'm a little surprised by this behavior. The auto-quoting function of = doesn't work quite as literally as I thought. It's working exactly as documented; = automatically quotes barewords, i.e., words that have no other meaning in the language. Strings of digits represent numbers in Perl, hence the hash keys must be quoted explicitly to be treated as text strings. In general, if your hash key is text that does not start with a letter or underscore, you should quote it yourself. If the hash key is text that contains anything but letters, digits, and underscores, you *must* quote it yourself. (There are some exceptions, but this approach is much less error-prone.) -- Eric Amick Columbia, MD ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

In any case, you will need either an argument list or an ampersand when

I looked in the source, and it appears the print statement is printing

Re: 16b hex conversion
It looks like you're doing this. Say if I'm way off-beam.
sub d2h16 {
sprintf %04.4X, shift;
}
I don't believe it. That's amazing. That's not off-beam,
that's nail on the head. Is there a way of returning that
as a value instead of printing it?
sprintf() already returns it as a string; it's printf() that prints to the default
filehandle. (As an aside, %.4X will produce the same result.)

im looking to access the unix 'fortune' program and need to iterate through

for (0 .. 100)
{
my $fortune = `/usr/games/fortune`;
print;
}
but it appears to create a bit of overhead in opening and closing a new
process for each call. it would be better to open a pipe or something and
just pass the handle the command if possible???
You can pass anything recognized by the shell within backquotes, so you
could always write a shell script that runs fortune some number of times
and then use
my $fortune = `/my/fortune/script`;
to get the output. You could even forego the separate script and enclose
the necessary shell commands in the backquotes instead. Since fortune
produces only one fortune each time it's run, this will only reduce the
number of processes created a little.

Re: How do I avoid the DOS window when starting a perl script
Have you tried using Windows Perl instead (wperl) ? You should find it in your perl/bin dir. This was posted a few months ago. :-) Someone pointed why there's no document on it. I think so too. But it *is* documented, though perhaps not as prominently as it should be. Read perlwin32.

Is SOAP::Lite with Perl for ISAPI Possible?
I've been trying to run a SOAP server with SOAP::Lite 0.55 under Perl 5.8.0 using Perl for ISAPI. The necessary extension mappings exist, but the debug trace always says something about no output being produced, and it apparently sends back a CGI header with a content type of text/html, which the client doesn't like at all. Is there some additional configuration required? The code produces the desired results when run as a normal CGI with perl.exe; it's just perlis.dll that has problems. -- Eric Amick Columbia, MD ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

Let me throw out another idea: $ = \n; print @array\n; No doubt someone will tell me how dreadful that is. :-) I also agree with the poster who asked why you chomped in the first place; is there really no way to work with the data with the newlines present? -- Eric Amick Columbia, MD ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
Re: regex expressions

I have the following string: $test = my brother is not ok today and i want milk for food I'd like to be able to place is not ok today in $1 and want milk in $2. Should be pretty easy, you simply start the search on my brother, place is not ok today in $1, skip the and, place want milk in $2 and you're done sort of like -$test =~ /my brother([ ])/ the result would be placed in $1, and $2 I'm trying to get a better understanding as to how one can quickly get to a group of chars that match a given term, do something, and then search for a subsequesnt group of chars All the examples I see use a single char as opposed to a group. In other words, how does one put a group of chars in a [] such that they will be used for an exact match??? I'm not terribly clear on what you're after. I *think* you want $test =~ /^my brother (.+) and i (.+) for food$/; The .+ matches one or more characters other than newline. The ^ requires the match to start at the beginning of the string, and the $ requires the match to go to the end of the string. You can also put any arbitrary list of characters in [], such as [A-Z,.;] This matches one uppercase letter, comma, period, or semicolon. As you can see, ranges can be used to save typing. There is plenty of information available if you use the command perldoc perlre; you might also have perldoc perlretut as well. -- Eric Amick Columbia, MD ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
