INV_MODULE

 ERROR:  The structure of the module is incorrect.

 USER ACTION:  If there are any syntax errors reported, fix them  and
 recompile.  If the error occurs before the first object declaration,
 check the syntax of the module header for  unwanted  ";"  characters
 after  the  module clauses, for example.  If the error occurs at the
 end of the module, check that the module concludes with  the  clause
 "end module;".
