Converting to hexadecimal or bit data (HEX-OF, BIT-OF)
You
can use the HEX-OF or BIT-OF intrinsic
functions to convert data of any type to hexadecimal or binary digits.
About this task
The HEX-OF intrinsic
function can be
used to convert data of any type to a human readable string of hexadecimal
digits ("0" through "9", "A" through "F", and "a" through "f") that
represent, in hexadecimal form, the underlying byte values of the
data to be converted. The length of the output hex string in bytes
is two times the length of the input argument string in bytes.
For
example, FUNCTION HEX-OF('Hello, world!') returns
'C8859393966B40A6969993845A'.
The
argument to the HEX-OF intrinsic function can be
a literal, a data item, or the result of an intrinsic function.
The BIT-OF intrinsic
function can be used to convert data of any type to a human readable
string of binary digits ("0" or "1") that represent, in bit string
form, the underlying byte values of the data to be converted. The
length of the output bit string in bytes is eight times the length
of the input argument string in bytes.
For
example, FUNCTION BIT-OF('Hello, world!') returns
'11001000100001011001001110010011100101100110101101000000101001101001011010011001100100111000010001011010'.
HEX-OF intrinsic function shown above and
corresponds to the EBCDIC encoding of the letter 'H'.The
argument to the BIT-OF intrinsic function can be
a literal, a data item, or the result of an intrinsic function.
