aditionl language: recognize space separated variabile names

Hello,

I customized the aditional Language files to tag the procedures names for the language which i’m using ( lisp based language ); Here the variable names ar declared something like:

let( var1 var2 var3 )

Is there any method to tag those variables (I’m interested for autocomplete, so I don’t care if there are more than one variable name in a file)

Thank you;
