It is implemented, (in Parse_Num_Factor() or something like that in 
express.c). But I couldn't find it in the section of the documentation 
with the string functions, although it was mentioned in other 
places(4.1.1  Identifiers and Keywords, 4.1.3  Float Expressions, etc).


I found it's definition in 4.1.3.6  Float Functions:

strlen(S) Length of S . Returns an integer value that is the number of 
characters in the string S .


This might need to be reorganized in the future, since although it 
returns a float value, it is definitely a string function.
