Operators determine how the information in a variable(s) should be evaluated in an expression.
There are several different types of operators - arithmetic, comparison and logical. Each has their own purpose. Arithetic operators are used to perform basic mathematical operations such as adding and subtracting. Comparison operators are used for relational and equality analysis in an expression. Finally the logical operators allows us to perform complex logical expressions.
The data type (numeric, string or boolean) will also be a factor in determining what operator you'll use. Here are some quick examples to get you in the mood:
Set Variable: "fname" = "Fred" Set Variable: "lname" = "Wahid" Set Variable: "salary" = 500 Set Variable: "salary" = 500 Set Variable: "overtime" = 120
Set Variable: "pay" = salary + overtime If (overtime > 300) Go to and Play("toomuch") End If If (fname ne "") Set Variable: "fullname" = fname & " " & lname End If
Let's begin with Numeric Operators...
