How to modify bytes in a binary file with RunRev

[titobal]

Hi all,

I would like to know if it is possible to modify bytes from a binary file using runrev ?

What I want to do for example is ... I load a binary file (which is a pure binary files filled with bytes),

then once loaded into a buffer I want to modify the 4th byte (offset $4) from the value it currently has (let say $80) into another value (let say $81 hex value)

then save this buffer into a new binary file...

How would you achieve that ?

Any help is greatly appreciated.

Thanks.

Hello,

Sure.

How would you achieve that ?

Load the file into a buffer, convert each character to a the hex value by using the baseConvert function. Make your changes and write the file back.

TIA.

you can also use the binarencode and binarydecode stuff, but if you're just beginning with rev, i suggest to try something else then binary stuff first.
