Re: Handling Hex data with Dynamic unpack

No doubt, I can decode the binary file this way.

I don't know many binary files represented as hex-text, so that won't work

Also, the format specification doesn't specify endianess so the format spec seems incomplete

I dont want to code with C kind of logic

:) But but but but, aren't you dealing with C-kind of data? Maybe Convert::Binary::C can help?

It is a BCD encoded binay file which is read in binary() mode. It follows a Big Endian notation. By C kind of logic, I meant the usual way of using loops etc.	[reply]

You might find the Template Grouping section of perlpacktut interesting, though I think writing some loops would be easier.	[reply]

Yes ... I did look through it and came up with some basic code ... but offcourse, I need to come up with complete code and then ask for other ways to handle the solution. Thanks ig :) for your reply.	[reply]

Sorry for the abbreviations. BER - http://en.wikipedia.org/wiki/Basic_Encoding_Rules DER - http://en.wikipedia.org/wiki/Distinguished_Encoding_Rules Its mainly the Telecom industry used standards	[reply]

Well, it is not following any of those BER or DER encoded binary file. Its just a plain binary file.	[reply]
