Hi All,
While using substring function, it ignores the trailing blanks , and i need to retain the trailing blanks of the string,
ex.
data b;
one= "abc ";
two=substr(one,3);
three=lengthc(one);
four=length(two);
run;
this is the output
one two three four
abc c 7 1
Replace four=length(two) with four=lengthc(two) and you will see that the trailing blanks are kept in variable two.
data b;
one= "abc ";
two=substr(one, 3);
three=lengthc(one);
four=lengthc(two);
five = cat('"', two, '"');
run;
proc print; run;
When you put a string into a SAS character variable that is shorter than the defined length of the variable, then it is always padded with blanks (unless you use substr() on the left side).
data test;
length x1 $5 x2 $10 x3 $20;
x1 = 'AAAAA';
x2 = 'XXXXXXXXXX';
x3 = put(x2,$hex20.);
output;
x2 = x1;
x3 = put(x2,$hex20.);
output;
run;
proc print data=test noobs;
run;
Result:
x1 x2 x3 AAAAA XXXXXXXXXX 58585858585858585858 AAAAA AAAAA 41414141412020202020
