The regex finds one or more digits \d+ followed by one or more
non-whitespace characters \S+. The parentheses define

As ever Kent, a neat solution. Much more efficient than
my 3 way search and relatively easy to

Hello,
I would like to read several parts of a string into different variables
based on the (physical) units of the quantities.
Here's my testing code:
