Re: Convert ANY to 16 digits number

[Peter Brawley]

Pseudocode for such a func would be ...

1 concatenate the 3 input strings

2 walk the string char by char, copying only digits to a new string

3 every 4th digit unless it's the last input char, add a hyphen

4 stop at 16th or 24th digit depending on input argument

5 Return the result string

Straightforward coding, just needs concat() substr() calls and a do...while loop with counters.
