Dear,
I need to split the value variable in to two variables (a and b ). I am able to extract first one using scan function. Please suggest which modifier i need to use in my code. Thank you
output need
a b
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
my code;
a=strip(scan(value,1,'('));
b=
Instead of a scan function, why not modify the INPUT statement to read in variables A and B directly?
The delimiter to use, in your case, is '(' only:
a = strip(scan(value,1,'(' ));
b = strip(scan(value,2,'(' )); /* or =strip(scan(value,-1,'(' )); */
@mkeintz meant:
data aa;
infile datalines dlm='(' truncover;
input a $ b $;
datalines;
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
;
run;

That's not quite what I meant, because I think the OP wanted to preserve the parentheses for variable B. I had in mind using the "@" directive in the INPUT statement:
data aa;
input a :$5.0 @'(' +(-1) b &$14. ;
put (_all_) (=);
datalines;
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
run;
Also, to read B, there has to be an "&" in the informat to prevent a single space from terminating the value.
Edited addition: And on further review I don't even need the "@" directive:
data aa;
input a :$5. b :&$14.;
put (_all_) (=);
datalines;
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
run;
Thank you all for helping. My question was I have a variable 'value' in my data with as below. I need to split the value in to variables 'a and b' as shown in output needed. For 'a' variable I am getting output I need. For 'b' i getting 0.32, 1.30) and 00.32, 10.30).
value
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
output needed
a b
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
code
a = strip(scan(value,1,'(' ));
b = strip(scan(value,2,'(' ));
Your SCAN function is using "(" as the word separator, which means it is not included as part of the word value, which is a problem for variable b.
You could prepend a '(' to b:
b = cats('(',scan(value,2,'(' ));

Thanks for providing data in usable form!
Instead of using "scan", a regular expression could be used:
data have;
input value $20.;
datalines;
5.00 (0.32, 1.30)
10.00 (00.32, 10.30)
;
data want;
set have;
length a b $ 20;
_rx = prxparse('/(.*\d) (.*)/');
if prxmatch(_rx, value) then do;
a = prxposn(_rx, 1, value);
b = prxposn(_rx, 2, value);
end;
drop _rx;
run;
Maybe the first part of the expression needs tweaking, depending on the other values you have.
You can also use the SUBSTR function:
data want;
set aa;
a=scan(value,1,'(');
b=substr(value,length(a)+2);
run;
This assumes that there's always one blank between the two parts of the string. If the number of blanks may vary (0, 1, 2, ...), the LEFT function could compensate:
b=left(substr(value,length(a)+1));
(Note that strip(...) in the definition of a is redundant.)
