concat: strange behaviour

[Frans Marcelissen-3]

Hi,
Could anyone explane this to me? I want tot add a substring tot a string. I use spss 18.0
 
string aa(a50).
compute aa=''.
compute aa=concat(aa,"second struing").
exec.
list aa.
 
This leads to a series of empty string.
This however works correctly:
compute aa=concat("second string",aa).
exec.
list aa.
 
 
Why?
Thanks
 
Frans

*------.
compute aa=concat(ltrim(aa),"second struing").
list aa.

Thanks. I see the reason, and the solution. I still thing this is very unexpected behaviour.

If you use Unicode mode (Edit>Options or SET UNICODE ON.) strings are right-trimmed automatically.  And I suggest using the char. functions in place of the older ones wherever they exist.
