Given data like the following:

B.3.54
A.14.1
BC.323.88493
ABC.1.4993

I need to always extract the first value after the first dot (reading left
to right). So, continuing in the example shown, I need to get: 3; 14; 323;
and 1;

This runs on one line at a time so I need to be able to just get one value
at a time copied into a variable. Can someone please post example code that
can do this?

Thanks much in advance.
