The PEEK.EXE program as distributed with this version is a very simple
   program which just gets the command line with a call to LIB$GET_FOREIGN
   and then passes it to PEEKSHR, a sharable runtime library.

   You may use this interface to integrate PEEK into your own applications,
   making PEEK a part of your product. By specifying the facility name
   parameter, you may customize the error messages to use your product
   name as a prefix.
