Before any programming takes place, it is up to you to decide what you would like the result to be.  For example, you might decide that when CHECKNAME is "0-1_check" that CHECKNAME1 should be 1.  There is nothing that SAS does on its own to make those decisions.

 

With just a few possible values for CHECKNAME, it might be as simple as this:

 

data want;

set have;

if checkname='0-1_check' then checkname1=1;

else if checkname='1-2_check' then checkname1=2;

run;

 

If there are many possible values to translate, you might need to create a rule that describes the outcome, instead of a list of values.  But it all starts with you making the decisions about what the result should look like.

A numeric variable in SAS can not contain characters.
