{ This program does the following:
  +------------------------------------------------------------+
  | * Makes sure the LIM Expanded Memory Manager (EMM) has     |
  |   been installed in memory                                 |
  | * Displays the version number of the EMM present in memory |
  | * Determines if there are enough pages (16k blocks) of     |
  |   memory for our test program's usage. It then displays    |
  |   the total number of EMS pages present in the system,     |
  |   and how many are available for our usage                 |
  | * Requests the desired number of pages from the EMM        |
  | * Maps a logical page onto one of the physical pages given |
  |   to us                                                    |
  | * Displays the base address of our EMS memory page frame   |
  | * Performs a simple read/write test on the EMS memory given|
  |   to us                                                    |
  | * Returns the EMS memory given to us back to the EMM, and  |
  |   exits                                                    |
