One simple way is to use SCAN() and tell that everything except digits are the delimiter characters.
So to get it as another character variable use something like this:
data want ;
set have ;
numb = scan(string,1,compress(string,,'d'));
run;
Or add an INPUT() function call to convert it to an actual number.
data want ;
set have ;
numb = input(scan(string,1,compress(string,,'d')),??32.);
run;
Obs string numb 1 E90K 90 2 G1006AfsX51 1006 3 W1001X 1001 4 R1014X 1014 5 D102A 102 6 G1036D 1036 7 R1035G fsX22 1035 8 R1035fsX1056 1035 9 . 10 C52AfsX8 52
So, does the numeric always begin in the second character? If so
data want;
set have;
string=substr(string,2); /* Throw out first character, we don't need it */
numeric=input(substr(string,1,notdigit(string)-1),10.0);
run;
There are a few cases start with a number
448 insG
639+5G>A
I want:

Are there any other cases we need to know about?

Tom, thank you and it works great!
Tom,
scan() has built-in modified option for this kind of situation.
data have;
input string $20.;
