Compute check digit.  See Taylor report Computerworld
1975 Usage: S Y=$$CCD^XLFUTL(X) Input: an integer.  Returns the input value
with the check digit appended.

Verify check digit (last digit).  Usage:  IF
$$VCD^XLFUTL(X) W "OK" Input: an integer with check digit, from $$CCD^XLFUTL
Output: 1 if the check digit matches, 0 for non-match.

Converts the first parameter from the number base of
the second parameter to the number base of the third parameter.  Usage: W
$$BASE^XLFUTL("1A",16,2) ==> 11010 Input 1: a string representing the number
to convert.  Input 2: a number from 2 to 16, the base of input 1.  Input 3: a
number from 2 to 16, the base for the output.

The useful values for Input 2 and 2 are 2, 8, 10, 16 but other numbers can be
used. e.g. W $$BASE("A",12,3) ==> 101

Because of the use of division, input is limited by the M vendor to the
largest integer they handle, 15 digits.
