Merry Monks,

I have a series of small text strings. Each contains a statement of a range of values, but in different forms:

1 - 5
3 to 24
6 thru 9
usually from 5 up to 12, but could be as much as 20 or more

I want to extract the numbers from the phrases so I can determine the max and min in the entire set of phrases. Making that determination is no problem, it's hw to extract the numbers.....

I can't always count on there being spaces between the numbers and the other text. A phrase could be mis-typed:

7-8

Thanks

Forget that fear of gravity,
Get a little savagery in your life.
