sas - Randoming symbols from a-Z

Question

I need to generate a string from random characters in range of a-Z. How can i do it?

Atm, i can only suggest randoming numbers in range of 1-52 and then reinitialize numbers with charecters. But that sounds awful.

Answer 1

CALL RANPERM seems well suited for this task.

25         data shuffle(keep=a: drop=addr);
26            array a[52] $1;
27            addr = addrlong(a1);
28            call pokelong(cat(collate(65,90),collate(97,122)),addr,52);
29            put @20 a[*];
30            seed=1234567890123;
31            do n=1 to 10;
32               call ranperm(seed,of a[*]);
33               put seed= @20 a[*];
34               output;
35               end;
36            stop;
37            run;
