No matter how many times you post this (at least three or four so far), it still won't make any more sense to most of us. Please give an example of the input and desired output. "Hex" and "Decimal" are far too broad to narrow down any possible algorithm. -- Randal L. Schwartz, Perl hacker	[reply]

Sorry for the confusion. an example of the hex file would be 40 30 4A 53 5B and an example of the decimal file would be 64 48 74 83 91 of course if you tried to open the hex file with notepad you would have jibberish, that is why I would like the conversion to dec. I know this can be done in PHP by using hexdec() and reading the whole file but I don't know how to do it in perl thank you and sorry for the confusion	[reply]

I'm even more confused. Why would opening a file that contains: `40 30 4A 53 5B` be gibberish in Notepad, or any editor? -- Randal L. Schwartz, Perl hacker	[reply] [d/l]

erm...if you open the file in notepad and it's garbage, my guess is it's a binary file. Either way, play around with `unpack` to extract what you want.	[reply] [d/l]
