Help creating a subroutine that parses a text file and adds it back to the subroutine to be printed out

csmith992 has asked for the wisdom of the Perl Monks concerning the following question:

I am very new to perl and I need to do the following: from a module name.pm file, find a text file, open it, find the string 0xF110000C00 and then on the next line after that I have to parse the string: 0x0402000000000100020003000400060007000800100000000000000000000000000000000000000 0000000000000 This would be version 04.02.00 and then continue to 0001 says slot 1, 0002 says slot 2, and so forth. Create a subroutine and in the perl module fru.pm that will Find the record in discovered information a. Parse the string into bytes b. Decode it into a HASH structure c. {version} {current} {major} {current} {minor} {current} {maintenance} {current}{patch} {current}{aux1} {current}{aux2} {backup} {major} {backup} {minor} {backup} {maintenance} {backup}{patch} {backup}{aux1} {backup}{aux2} {fruid} Return the hash d. If optional param is true, print a nice table of this output e. Usage: $sys->{'1_2'}{slot}7->getFUMIStatusRecord() This is not for a class. This is for my knowledge only. Any help would be appreciated. I am using linux. Thanks, Craig

What does your current code look like and how does it fail? Even more so when your avowed intent is learning than with homework it is important to show what you have tried and to show that you have made an effort. You learn almost nothing if we give you an answer (even if we could understand what you are trying to do). But you will learn a great deal, even if you fail to achieve what you set out to do, when you have a good go at solving the problem for yourself first. You may find perlretut, substr and (maybe) unpack helpful. True laziness is hard work	[reply]

This looks like a class assignment that is way over your head! That is obvious due to the framing of the question like: "from a module .pm file". The description of the problem does not describe the desired end result. I have no idea what "0xF110000C00" means. The second line could mean like this: `0x040200 0000 0001 0002 0003 0004 0006 0007 0008 0010 0000 0000 0000` [download] I have no way to help you without more information.	[reply] [d/l]
