Isn't this pretty much the same thing as ITYPE(), except the conversions
are processed?
In the CALCULATE() form, the dictionary.item can be a quoted string
or a UniBasic variable. The expression uses the data from the current
@RECORD during the evaluation process.
In the {} form, the dictionary.item must be the literal dictionary
name with no quotation marks.
You must open a dictionary to @DICT and read the data record into
@RECORD for the function to work properly.
If these functions are successful, they update the values in @CONV,
@FORMAT, and @HEADER. You can then use these @ variables in other
UniBasic functions, such as ICONV, OCONV, and FMT. For more information
about @ variables, see Appendix B, "UniBasic@variables."
-----
The UniBasic ITYPE function enables a UniBasic program to execute
a UniData virtual attribute from the dictionary of a UniData file.
The value of the function is the same as if it were run using UniQuery
or UniData SQL.
Note: ITYPE generally requires you to open both the dictionary and
data portions of the file. Before you use this function, you must
compile the dictionary of the file by using the ECL COMPILE.DICT
or CD command.
In most cases, you also must assign the @ID and @RECORD variables.
These variables resolve the value of the ITYPE function. However,
if neither the ID of the file nor the data from the record is used
in the ITYPE, you do not need to assign these variables.
Note: Conversion or formatting codes in the dictionary record of
the virtual attribute does not affect the value ITYPE returns.

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

Of course. Worked like a charm.
Thank you Dave.

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?
