Binary Statements represent expressions consist of two operands (variables, strings, numbers, methods...) and an operator (e.g. +, -, *, <, <=, !...).
Binary statement in Manual view
Open a test case in Manual view, then navigate to Binary Statements from command toolbar.
A test step represents binary expression is added to the test case.
Double click on the Input cell to edit the binary expression.
Save the test case when you're done.
Once a test step is added as any of the Binary Statements, it will not be allowed to change it into another keyword.
Binary statement in Scripting view
The Script view of test cases allows you to programmatically define and handle binary expression easily using either Groovy or Java language. Refer to http://groovy-lang.org/operators.html for more details about using operators in Groovy.
