https://www.freepascal.org/docs-html/rtl/sysutils/bytesof.html
The abstract is  "Return the bytes in a string". Probably you can blame 
my English, but I think it is ambiguous whether  it must be read as

Return (the bytes (in a string))
or
return (the bytes) -> (in a string)

before reading the function declaration, I thought it was the second case.

better something like "Return the bytes OF a string in an array of bytes 
TBytes"
