Stored Procedure and VarChar Content Length

I have a stored procedure with a couple of variables defined as
follows:

Declare Str1 VarChar(3000);
Declare StrLen Dec(15,5);

I then build the value of this variable with several
concatenations. How do I then set the second variable to the length of
the content of the first? I guessed at it and the following seems to be
correct.

Set StrLen = Length(Str1);

But I don't like having to guess. Where do I find documentation
on such things? Thanks.

Sincerely,

Dave Clark
