How do I reset an array?

Mission has asked for the wisdom of the Perl Monks concerning the following question:

I am writing a text file, where I'm substituting characters on the fly. For example I'm using an array with a split and replacing spaces of my string for '%2B'. At the end of each line (for loop) I want to reset the array so it will start over. It's doing much more than that, but I hope you understand my goal. Can someone please point out my mistake (or the obvious)?

Appreciatively,

- Mission

you don't actually need to reset the array... if you are using split it will do it all by itself: `@array = split(/-/); # will create the new array @array # later on... @array = split(/-/); # will empty the array and create a new array @ar +ray with the new values` [download] don't write code that doesn't do anything... Update: did you say "substituting spaces..." and "using an array and split" ??? are you sure you're using the right`(s///)` command ??? He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.	[reply] [d/l] [select]
Too Brief? by Mission (Hermit) on Apr 10, 2001 at 23:35 UTC
Chady, I like your signature file... I feel like the five minute fool for asking such a basic question. To answer your question, yes I am using the s/// command. The file I'm trying to write has some bizarre formatting for another application. It has it's own special line counting and EOL characters, so I was splitting to rebuild the character count per line and line count per story for multiple stories. I apologize for being too brief in my initial question, and thanks for the array help... I'm very new to all of this (as you can tell.) *- Mission* "Heck I don't know how to do it either, but do you think that's going to stop me?!!"	[reply]

Depends what you mean by reset. To clear it: `@array = ();` [download] To restore to its old value: `@save = @array; for (@array) { # Loop stuff } @array = @save;` [download]	[reply] [d/l] [select]

You might work on a splice of your array like `@arry[1..@#arry]` in your for loop but as I wonder why you are doing all lines again and again - did you consider to use Math::Matrix ? {grin} Have a nice day All decision is left to your taste	[reply] [d/l]
