NONPVT

 ERROR:  A private value is one that is not imported or exported.  In
 the  context  marked  by the message, only a private value is legal.
 Situations where this message is issued include:  defining one value
 in  terms  of  another;  and  arguments to functions.  In general, a
 value must be private when the  compiler  must  know  the  value  at
 compile  time.   Exported  values  are disallowed in these contexts,
 even though  a  value  is  present,  because  that  value  could  be
 overridden at run time.

 USER ACTION:  Change the value to be private.
