An expression is made up of variables, functions, and field values from databases. A value can be calculated and either printed or displayed in a report.
Code in an Expression
If you know the programming language of a report, you can include code when calculating the value of an expression. Use curly braces (“{“ and “}”) to separate code from other text. When utilized, the result of a calculation will be converted into a string.
Value = {5 + 3}
The result of this expression in the report:
Value = 8
Multiple Code Insertions
There is no limit to the number of code insertions permitted in an expression.
A = {7 + 2}, B = {6 + 1}
The result in the report:
A = 9, B = 7
Nested Code Insertions
Nesting of code sections in an expression is not permitted. As an example, the following expression will result in the calculation failing:
Value = {5 + 3 + {2 + 1}}
