The IDENT attribute can  be  used  to  qualify  the  name  of  a
  compilation  unit.   In  the  absence of an IDENT attribute, the
  string '01' is supplied to the linker.

  Syntax:

     IDENT( name-string )

  The 'name-string' can contain additional information  whose  use
  is  implementation  specific.  The VSI Pascal compiler uses this
  string to supply identification information to the linker.
