Hello,
I'm looking to strip the last character of a string only if it is ")". Have:
Data_values
%
%)
mg/l
mg/l)
Want:
Data_values
%
%
mg/l
mg/l
data want;
set have;
if reverse(trim(data_values))=:')' then data_values=substr(data_values,1,length(data_values)-1);
run;
The REVERSE() function looks at the last character, if it is a ')' then we delete it using the SUBSTR() function.
The REVERSE() function is very much underappreciated and I think SAS should sponsor a "Reverse Function Day"!
