In Unidata I believe that it only works for virtual (type = V) attributes. 
 It is nice though. If you have an attribute that reads  from other files 
and performs calculations, formatting, etc. it executes the virtual and 
gives you the output.  Let's you take advantage of the virtual attributes 
already defined in the dictionary.

Is that only a Unidata thing? Sounds like a nice feature to have in 
Universe.....

HELP CALCULATE

You have to have your dictionary open to @DICT as well.

I think you want to say

RESULT = CALCULATE(ATTRIBUTE)

Since {} is for a literal attribute name only.

Subject: [U2] @RECORD VARIABLES

I am attempting to pass a variable into a SUBROUTINE and use it to access 
the data through the dictionary name.

SUBROUTINE fieldLookup(....., ATTRIBUTE, ....) .
.
.
READ @RECORD FROM F.FILE, @ID THEN
        RESULT = {ATTRIBUTE}
END ELSE
        RESULT = ""
END

The part that isn't working is the RESULT = {ATTRIBUTE}

As written here it is looking for a dictionary attribute named ATTRIBUTE.
I tried forcing it to evaluate the variable ATTRIBUTE to the value in 
ATTRIBUTE by putting it in parenthesis, but it complained that it was 
expecting a variable when it was compiling.
Is there a way to use a variable in the curly braces so that I can make 
this a generic subroutine?
