Create new variable in sas, which is equal to the first digit of another variable -

I have a data set in SAS, which looks like the following:

2. 1 3454
3. 4 4231
4. 5 5343

named variable From the disk, I want to create a new variable, which is equal to the first digit of the disco variable:

1. The person disco new_disco
2. 1 3454 3
3. 3 4534 4
4. 4 5 423 4
5. 5 5343 5

I also want a numeric variable to be a numeric variable.

Thank you

You get the substr () and < Code> input () functions need to be aligned:

  data is new; Old set; New_disco = input (substr (disco, 1,1), 8.); Run;
