The Question is:

 
Please could you help me find the documentation that will help me write
programs that use the QIO$ interface to UCX. I will be using BASIC.
Thanks very much.
 
 

The Answer is :

 
  Source code examples for most Compaq products and packages are generally
  available from DSNlink, and directly from the customer support center.
 
  OpenVMS uses a calling standard -- all programs use the same mechanisms
  to call programs.  Each language has language-specific behaviour around
  specifying mechanisms such as pass-by-value, pass-by-reference,
  descriptor-by-reference, and itemlist-by-reference.  The underlying
  OpenVMS mechanisms are all identical, across all languages.  This means
  that you will want to understand the OpenVMS calling standard and how the
  calling standard applies to your particular language.
 
  UCX$EXAMPLES provides various C examples of sys$qio and sys$qiow calls.
