this is a snippet of a file i'm trying to process: ### iotests ( WriteEmUp [create:openwr:write:close] ReadEmUp [openrd:read:close] ) i need my perl regex to recognize "iotests", then make anything that matches ".[.]" into a string. I can't count o

i really hope thats overkill for my problem. I have my program finshed, this is the last condition i have to deal with. Also, my supervisor would prefer me not to use any nonstandard modules. On 7/5/06, Tom Phoenix <[EMAIL PROTECTED]> wrote: On 7/5/06, Ryan Moszynski <[EMAIL PROTECTE

processing a hash of a hash of a hash

I am trying to print out a hash of a hash of a hash table(with code chunk 1), but I keep getting the following error: Use of uninitialized value in hash element at ./clearwhite.pl line 522. I don't understand where this error is coming from since I can process a hash of a hash just fine, using

regex repetition

I need to write some code to allow users to specify which of a whole bunch of elements(e.g.512/1024) that they want to view. My idea for how to do this was to have them input a semicolon delimited list, for example: 1-10;25;33;100-250 i tried using this to check to make sure they input a valid

awesome help, but, a question

Mumia, thanks for your work on answering my help request. I really appreciate it. However, while your solution works perfectly in your sample program, since I am new to perl, I am having trouble understanding some of the techniques you used, and i am having trouble integrating the solution that

passing a list as a variable

Is there a way to make my commented 'foreach" line act the same as the line above it? Can I pass a list as a variable as I am trying to do, or doesn't perl support that? ### #!/usr/bin/perl -w $|=1; #use strict; system "clear"; my @array = 1024; my $list4 = "0..10,33..43,100..111";

Re: passing a list as a variable

# Argument "0..15,33..43,100..111" isn't numeric in array element ### i guess a better question is, can I ?cast? that string into a variable that can be recognized by the foreach? On 7/24/06, Joshua Colson <[EMAIL PROTECTED]> wrote: On Mon, 2006-07-24 at 12:40 -0400, Ryan Mos

Re: passing a list as a variable

thanks guys. Dr. Ruud's solution does the trick. I was trying to get around having to do that, but i guess you can't have everything. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

perl default variable question

hi, i'm using a perl script i found to change the names of batches of files. The program works as is but it's giving me a weird warning. I'm familiar with $_, but not $_[3]. Can someone explain what $_[3] is, and how i can get this script to stop throwning the warning? Thanks, Ryan i found the

socket client, can't print w/o newline

first off, i apologize if i'm not describing this as succinctly as possible. i'm working on some client/server stuff using sockets, and i grabbed some code from the net that i don't totally understand. i'm passing packed messages back and forth over a socket from the client/server. Right now i h
