sas - How to use tranwrd in a data step? -

-

i try substitute y x
tried used tranwrd function in data step . result 1 row 

data test2 ;  set test  ; address =  tranwrd(address , 'y' , 'x' ) ;    put address ; run;

test data follows

    id  address     1   123 y street     2   234 y street     3   345 street

the code, written, should work. removing put line prevent each line being written log (this speed things if have large data set):

data test2 ;  set test  ; address =  tranwrd(address , 'y' , 'x' ) ;    run;

the address = tranwrd(address , 'y' , 'x' ) ; adequately defines variable value.

the put statement writes value of address sas log @ point in data step.
