Dear,
I need to have the 'test'value without the charaters in parenthesis. I am using scan function. Is there any better way to get the output. Please suggest. Thank you
Output needed:
term1
Urine Choriogonadotropin Beta
data one; input test $ 1-35; datalines; Urine Choriogonadotropin Beta (NA) ; run; data two; set one; term1=scan(test,1,'('); run;
Assuming the characters in paranthesis is at the end of the string in all records if present.
data one;
input test $ 1-35;
datalines;
Urine Choriogonadotropin Beta (NA)
;
run;
data two;
set one;
substr(test,index(test,'('))=' ';
run;
Regards,
Naveen Srinivasan
Or if you need to remove all brackets no matter where they are in the string:
data one;
input test $ 1-70;
datalines;
Urine Choriogonadotropin Beta (NA)
Urine Choriogonadotropin Beta (NA) something (something else)
;
run;
data two;
set one;
/* create variable term1 with the same length as test */
if _n_=1 then term1=test;
/* remove everything in brackets from source string */
term1=prxchange('s/\s*\([^\)]*\)//o',-1,strip(test));
run;
You can do it in one data step. e.g.:
data one; length test $50; input @; if index(_infile_,'(') gt 0 then _infile_=substr(_infile_,1,index(_infile_,'(')-1); input test &; datalines; Urine Choriogonadotropin Beta (NA) Urine Choriogonadotropin Alpha ;
