I have ICD 10 codes from 1 to 10 listed.
I would like to combine all codes values if any listed ICD 10 codes start with A. How can I do that? Thank you.

Example fake data:

Code1 code2 …code10
H25 G45
J257 D467 A56
A46 A56
F35 D456 A456 Y366

Wanted data would be keep all values when start with A.

Here is basic logic for looping over an array or variables and checking if ANY of them meet some condition.

First set the overall result to FALSE.  Then loop until you run out of elements or you find one that it TRUE.

data want;
   set have;
   array code [10] ;
   any_a = 0;
   do index=1 to dim(code) while (not any_a);
      any_a = code[index] =: 'A';
   end;
   if ANY_A then output;
run;

You should explain what you mean by "combine". If you mean to place multiple values into one variable that is likely to become a variable that is extremely difficult to work with.
