Reading the online documentation for the transwrd function I found two import sentences:
"If the TRANWRD function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 200."
and
"The value that the TRANWRD function returns has a default length of 200. You can use the LENGTH statement, before calling TRANWRD, to change the length of the value."

While running the following program, the result from  proc print & proc content:  for  'address' length is 200 & value is '201 London drive' as well as for 'address1' length is 14 & value is '201 London fly'.

data abc;
address1='201 London fly';
run;
data abc;
set abc;
address=tranwrd(address1,'fly','drive');
run;

proc print data=abc;
run;
proc contents data=abc;
run;

SAS Output
