DECLARE INTEGER ntohs IN ws2_32 INTEGER netshort
DECLARE INTEGER ntohl IN ws2_32 INTEGER netlong
DECLARE INTEGER htonl IN ws2_32 INTEGER hostlong
DECLARE INTEGER htons IN ws2_32 INTEGER hostshort

* HOST to NET  u_short -- htons
* NET  to HOST u_short -- ntohs
* HOST to NET  u_long  -- htonl
* NET  to HOST u_long  -- ntohl

? "*** Working with U_SHORT values"
lnFtpPort = htons(21)
? "Converted to the network byte order:",lnFtpPort
? "Host byte order again:", ntohs(lnFtpPort)
?

? "*** Working with U_LONG values"
lnTelnetPort = htonl(23)
? "Converted to the network byte order:", lnTelnetPort
? "Host byte order again:", ntohl(lnTelnetPort)

DECLARE INTEGER inet_addr IN ws2_32 STRING cp
DECLARE STRING inet_ntoa IN ws2_32 INTEGER in_addr

* The inet_addr function converts a string containing an (Ipv4) 
* Internet Protocol dotted address into a proper address 
* for the IN_ADDR structure
? "*** Converting IP addresses"
lnIP = inet_addr("127.0.0.1")
? "String value converted into a proper address:", lnIP

* The inet_ntoa function converts an (Ipv4) Internet network address 
* into a string in Internet standard dotted format
? "Converted back to a string value:", inet_ntoa (lnIP)
