  Writing a TCP/IP ICMP ping program? 
 The Question is:
 
Is it possible to write a program to ping hosts using "Digital TCP/IP
Services for OpenVMS" (UCX).  I need to be able to use the QIO interface as
I have no access to the C routines. If it is possible please could you point
me in the right direction.
 
Thanks - Malcolm
 
 The Answer is:
 
  There is a program provided with the TCP/IP Services for OpenVMS package
  that performs this particular task: the ping command in the UCX (versions
  prior to V5.0) or TCPIP utility (V5.0 and later).
 
  If you wish to write a program that generates and receives ICMP requests
  over an IP network, you can use the sys$qio[w] interface documented in
  the TCP/IP Services for OpenVMS documentation.
