Protection bits of amiga lha-archives

jbl007 · 23 August 2014, 21:52

Hi,

does anyone know a semi-noob-friendly way to get the protecton bits of a file in an lha archive? From my understanding they are stored in 1 Byte at offset 19 of the file header.
Some examples I discovered while testing:

Code:

0x00: ----rwed
0x40: -s--rwed
0x04: ----r-ed

Thanks in advance.

Edit:
I think, I've got it. It's easier than I thought.
Just convert the hex value to binary, invert the last 4 bits (because ----rwed is 0x00 and some kind of default) and you are done. Am I right?
