CALCULATE
Syntax
CALCULATE(dictionary.item)
{dictionary.item}
Description
The UniBasic CALCULATE or {} (braces) function executes a virtual attribute. The
dictionary.item must be a valid virtual attribute within the dictionary previously
opened to the @DICT variable with an OPEN statement.
Note: Before you use this function, you must compile the dictionary of the file you will
open to the @DICT variable by using the ECL COMPILE.DICT or CD command.
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.”
