substitution of varying digits
I had a requirement in which in need to pan(*) out digits except the first six visible, followed by six *, and rest
visible of a variable(input)

ex:
Input - 123456789012345
Output - 123456******345
ex:
Input - 1234567890123456
Output - 123456******3456

so i tried something like below and it worked.
Code:
if($length($(i+12))>=15)
   
  {sub(substr($(12+i),7,6),"******",$(12+i))}

But now the updated requirement is that I need only the first six and the last 4 to be visible and the
rest(will vary depending upon length of input) replaced by * for any
length greater or equal to 15.
Please Advice how to achieve the above.
