FYI: For those using DEC Ada, it is not necessary to write such
     a routine in another language.  One can use the VAX/VMS
     System Services Package which has the QIO & QIOW routines
     in an Ada Package interface. 

     I've done this before, unfortunately the source is not
     immediately available.  It is not difficult though.
