Reading unsigned bytes from file

Hi all!

I am sure this is a simple one. I want to read one or more bytes from a file. I want to use the unsigned value of each byte in calculations. I don't want negative values. Anyone?

regards,

if I remember correctly

value & 255 ; I think

yep, but you must store the result of 'value & 255' i something like WORD or LONG.
If you store it in a BYTE again, you'll get just the same signed thing

So obvious, and yet I couldn't figure it out!

Thank you!
