"16-bit File Checksum"
Finds the 16-bit checksum of a file.
The checksum is the sum of the ASCII values of all of the characters within the file.
Checksum is returned as a Long (Integer) value between 0 and 65,536.
Uses modulo addition so that the function will return the 16 least significant bits of the sum.

       Checksum16("ABCD") = 266
       StringToFile("ABCD", "C:\Test.Out") = True
    for example
       Checksum16File("C:\Test.Out") = 266
