DTM performs the following steps when it executes tests
  within a collection:

  1. Defines the DTM$COLLECTION_NAME variable as the
     collection name

  2. Defines any global variables with values as assigned
     when the collection was created

  3. Executes the collection prologue file, if any
     perform the

  4. Calls a generic command file in the DTM library to
     following tasks for each test:

     a.  Defines local variables

     b.  Defines the DTM$TEST_NAME variable as the test
         name for the current test

     c.  Executes the test prologue, if any

     d.  Executes the test template

     e.  Defines the DTM$RESULT variable as the test
         result name of the current test

     f.  Executes the test epilogue, if any

     g.  Executes any user-defined filters

     h.  Executes filters provided by DTM

     i.  Undefines local variables

     j.  Undefines the DTM$RESULT variable

  5. Compares the result file with the benchmark file

  6. Executes the collection epilogue file, if any
