Hope this helps:
The BYTEORDER procedure converts integers between host and network byte
ordering or floating-point values between the native format and XDR (IEEE)
format.
Calling Sequence: BYTEORDER, Variablen, /keywords
Variablen=A named variable (not an expression or constant) that contains the
data to be converted. The contents of Variablen are overwritten by the new
values.
Keyword HTONL: Set this keyword to perform host to network conversion,
longwords.
