StrLen of an Attribute

[Nicolas Breuer]

Ok Alan so what is the correct syntax please ?

I saw in the doc
; %{#string}
: The number of characters in %{string}.  If %{string} is not set, then the length is not set.  This will NOT work for the one-character variables defined below.
: e.g. %{#Junk-junk:-foo} will yield the string "foo".

But ok this is not a string.

  Yes.

  Because Service-Type isn't a string.  It's an attribute of type "integer".

  And why would you ever need to look at the string length of it?

  And why would you use "(%{#%{reply:Service-Type}}"   ? You're inventing syntax here.  Nothing in the the documentation says that you can use:

${#

  Much less

%{#%{reply:...

  You can't just invent things and expect them to do what you want.  Computers don't work that way.
