System generated codes

Dear All,

How can AbAa, AeAi, AmAp, AfAd, AtAc, . . .   be converted to the code   01, 02, 03, 04, 05, . . .

where the codes 01, 02, . . . are generated by the system? 

I have two columns (variables) of character values as shown above with some of the values repeating,

and I would want to be able to tell which character value was converted to which code. Each variable

holds thousands of values.

Thank you.

System generated codes

In order to get the most useful help, you would have to provide more info, specifically regarding how you want to use these codes.

You can always sort the dataset by the field's values and include the nodupkey option to generate a sorted list of the unique values, create the desired number references by creating a field based on the values of _n_ but formatted using the zW. format, and then use proc format with the cntlin option to automatically create the formats or informats that you want.

A nice paper on how to do that can be found at: http://www2.sas.com/proceedings/forum2007/068-2007.pdf
