How to isolate number from a variable containing numbers and text

Dear,

 

In my data, a variable name 'Totaldailydose' contain numbers and text. I need to convert the numbers only into numeric form in my output.

 

ID                           Totaldose

 

1                          EVERY 3 YEARS
2                          1 DEVICE EVERY FIVE YEARS
3                          1
4                          900
5                          2000
6                          300
7                          UNKNOWN

 

 

OUTPUT needed;

 

ID                 Totaldose

 

3                  1

4                  900

5                  2000

6                  300

 

my code worked but gave me some warning messages. Please help. Thanks

totaldose= input(totaldoailydose,best.);

If all you want to do is suppress the warning messages about invalid data, a double question mark will do the trick:

 

totaldose= input(totaldoailydose,??best.);
