"OC192-11,OC192:PSD,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1"

"OC192-12,OC192:CVS,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1"

"OC192-12,OC192:ESS,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1" ';

output array:

var1 = '"OC192-11,OC192:ESS,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1"',

var2 = '"OC192-11,OC192:PSD,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1"',

var3 = '"OC192-12,OC192:CVS,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1"',

var1 = '"OC192-12,OC192:ESS,0,COMPL,NEND,RCV,1-DAY,02-11,00-00,1" '

Find the array element as per the pattern., Row wise print the values when convert the cvs file ., text to csv file format, and now this current thread, all dealing with the same issues. This isn't going to get any easier until you make the conscious decision to learn Perl, and follow it up with study and practice. If that's not the goal, it might be worthwhile hiring someone to finish it up for you. What part of this script do you intend to write yourself? I would start with the O'Reilly book, Learning Perl. It's a great resource. Dave	[reply]

Maybe the '#!/usr/bin/perl' part? Or am I being too optimistic? ;) Elda Taluta; Sarks Sark; Ark Arks My deviantART gallery	[reply]

With split. See also: perlretut, perldsc, perllol. Perl 6 - second systems done right	[reply]

For the moment forget about "how", but instead tell us about the "why". Your code does not match your descriptions and the input and output arrays appear to be identical. Paint us a bigger picture to show us what you are trying to achieve - not just in terms of an input array and output array, but what you want the full script to achieve. True laziness is hard work	[reply]

BTW, `push (my @newarray, ... );` [download] can (or should) more clearly be written as `my @newarray = ... ;` [download] because the `push` suggests that you're intending to add values to an already existing array. The `my`, OTOH, creates a new array every time you execute the statement, so the effect is the same as a simple assigment...	[reply] [d/l] [select]

Well, we’ve always heard of “the XY problem,” and here we see where those kinds of problems come from. When you are struggling to learn a language (or, struggling to use it without taking the time to learn it first...?), it does not pay to be a bulldog. You will consistently find that, having grabbed on to that first toy and worked very hard to shred it completely into tatters, you have, in the end, accomplished nothing useful at all. Oh, “you wrote a program,” all right, and eventually you even got it to work! Unfortunately, the same task could have been accomplished with a “one-liner” in Perl or even `awk`. If you didn’t first take the time to study the problem and to determine what is the best all-around way to solve it, you are spinning a little wheel in a little cage. Folks who take that approach “wash out” very quickly, as they are a waste of time and money for their employers, anywhere in the world. Remember, this is engineering.

Might I take this thought further and speculate that many who do wash out have the problem of "a small toolbox"? When all you know how to use is a hammer, you try and refactor each problem into a nail.	[reply]
