Quentin,

YOu are right, there is a leading space, if you want to
see that space, you need to use $char. format:

58   data null;
59   length str $100;
60   str='one two three';
61   str=tranwrd(' '||trim(compbl(str)),' ',' new');
62   put str $char.;
63   put str;
64   put str= $char.;
65   run;

 newone newtwo newthree
newone newtwo newthree
str=newone newtwo newthree

One thing I don't understand either is that why
put str= $char. dose not show the leading space.

Ya

Ya Huang provided a nifty solution:

I would have expect so see a leading space in STR:
 str= newone newtwo newthree

Why isn't there one?
