How to get number between 0 and 9 and letter between a and z which are not found in a variable

[alepage]

Hello,

In one of my table, I was able to pick all the code that are used in our programs which may vary between 0 and 9 and between

a and z.

For example if my codelist = 1 2 3 4 x y z then I would like to find a way to obtains the one that are not in our codelist such as

0 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w.  How to do that?

Regards,

Please explain more about how you have the current data.

If you have strings you might try the COMPRESS() function.

601   data test;
602     length all some rest $36 ;
603     all = collate(rank('0'),rank('9'))||collate(rank('a'),rank('z'));
604     some='345bcdegh';
605     rest=compress(all,some);
606     put (_all_) (=/);
607   run;


all=0123456789abcdefghijklmnopqrstuvwxyz
some=345bcdegh
rest=0126789afijklmnopqrstuvwxyz
