/OLD_VERSION

  The /OLD_VERSION  qualifier  is  provided  for  compatibility  with  early
  versions of HP BASIC for OpenVMS VAX.

  The format of the /OLD_VERSION qualifier is as follows:

     /[NO]OLD_VERSION[=CDD_ARRAYS]

  When you use the /OLD_VERSION qualifier, the compiler  changes  the  lower
  bound  to  zero  and  adjusts  the upper bound of the array.  For example,
  Array 2:5 in CDD/Repository is translated by the compiler to be  an  array
  with  a  lower bound of 0 and an upper bound of 3.  The compiler issues an
  informational message to confirm the array bounds.

  The /NOOLD_VERSION qualifier causes the compiler to extract an array  from
  CDD/Repository  with  the bounds as specified in the data definition.  For
  example, Array 2:5 in CDD/Repository is translated by the compiler  to  be
  an array with a lower bound of 2 and an upper bound of 5.

  CDD/Repository assumes a default lower bound of 1, if none  is  specified.
  Therefore,  if  no  lower  bound is specified, the compiler translates the
  CDD/Repository array to have a lower bound of 1.  For example, Array 5  in
  CDD/Repository  is  translated by the compiler to be an array with a lower
  bound of 1 and an upper bound of 5.

  The default is /NOOLD_VERSION.
