////  Name: readFlashPagesToBinFile
////
////  Purpose: Reads a page of flash memory and writes it to a BINARY file.
////           The user is prompted for, and provides, the file name and the
////           page number.  The user can choose an ALL_PAGES option, which
////           will copy all 8 of the flash page to the file _in order_
////           (ie, it will copy page 0, then page 1, etc).
////
////           A flash page on the EVM-DM642 is 1/8 of the total flash
////           memory.  It contains 8 full sectors.  And is 512 KB.
////           [Thus, copying ALL pages creates an ~4 MB BINARY file]

////  Input Parameters:
////      hDM642 - Handle of the currently-open DM642 board/card
////
