Yeah, that cabe help is incorrect.  I don't ever remember len being able 
to take a literal expression.
The online manual at fptech does state " Where "f "is a dummy or real 
field", although you can use a long variable name in the function which 
can be uncast for length (fp v. 5.0.14):

Then: declare origexp(40,*)

Then: origexp = "testing"
.
.
Then: declare shortexp

Then: shortexp=""{origexp{""

Then: msgbox "Length of trimmed origexp = "<len(shortexp)


This len function here will return "7".
