Hello I am just trying to figure out a simple substr command:

data a;

input A B @@;

datalines;

123 ABCD

;

run;

data a; set a ;

if substr(B,1,1) = "A" then type ="S";

else type='K';

T = substr(B,1,2);

run;

Not sure why this code is not working, it just always defaults to K. Any ideas?

Run the first data step only and then check what you've actually got in table 'a'.

Also: Always read the SAS log as it gives you valuable information, eg:

NOTE: Invalid data for B in line 18 5-8.

Thanks Patrick, I'm still a novice to SAS, I'll take your advice in running parts of the code each time.  Made the correction and it worked fine:

data a;

input A B $ @@;

datalines;

123 ABCD

;

run;

data a; set a ;

if substr(B,1,1) = "A" then type ="S";

else type='K';

T = substr(B,1,2);

run;
