True. EBCDIC or ASCII only describe the hex code used to represent a character, like the letter B is x'42' (ASCII) or x'c2' (EBCDIC). It wouldn't apply to packed decimal, binary, or floating point. Negative 12345 in binary would be x'cfc7' regardless of how other alphanumeric fields are coded in the record where it resides.
