I don't know where to get the byte from, but if you have a byte variable you can store it in a data table.
Also, you can convert bytes from and to integers in custom scripts, this is already done implicitly.
But remember, when converting an int to a byte, the resulting byte will contain only the lowest 8 bits of the integer.
I cannot see that you can use it like an integer or convert it to or from one... so what can it be used for?
@BeLugh: Go

Don't think the variable type "Byte" is useful nowadays. It had its use 15-20 years ago to help save some memory.
