You need to use BYTEORDER:
ROUTINE:
BYTEORDER, Variable_1, ..., Variable_n
DESCRIPTION:
BYTEORDER converts integers between host and network byte
ordering or floating-point values between the native format
and XDR (IEEE) format. This routine can also be used to
swap the order of bytes within both short and long integers.
If the type of byte swapping is not specified via one of the
keywords below, bytes within short integers are swapped
(even and odd bytes are interchanged).
