Result

The BCD to Binary conversion function converts a BCD Conversion
number into a binary number. Its function number is 13 and the
conversion takes the form:

0xx xxx = y yyy

Important: When the result is displayed using a Get instruction, only the
first 12 bits can be seen. Use a SEARCH 53 to look at all 16 bits.
