data test;
var="AAA123BBB22CC555";
newvar=translate(upcase(var),"","ABCDEFGHIJKLMNOPQRSTUVWXYZ");
run;

sorry,我举的例子不准确，因为不光是英文字母，中间还会有中文

同问~

我没用过中文版的SAS，也没处理过中文的值，我用的方法是把数字提取出来，并且保留了之间的空格，你试试行不行

data test;
length var $100;
var="AAA123BBB22CC555";output;
var="123AAABBBCC333DD2244DDD"; output;
run;

proc sql noprint;
select max(length(var)) into: num
from test;
quit;

data wanted;
set test;
array subvar[*] $1. var1-var%left(&num);
do i=1 to length(var);
  if substr(var,i,1) in ('1','2','3','4','5','6','7','8','9','0') then subvar[i]=substr(var,i,1);
  else subvar[i]='';
end;
newvar=cat(of var1-var%left(&num));
keep newvar;
run;
