Explanation:

Operators

There are various types of operators discussed in this appendix. The following types are provided:

Arithmetic Operators are used to perform mathematical calculations.

Assignment Operators are used to assign a value to a property or variable. Assignment Operators can be numeric, date, system, time, or text.

Comparison Operators are used to perform comparisons.

Concatenation Operators are used to combine strings.

Logical Operators are used to perform logical operations and include AND, OR, or NOT.

Boolean Operators include AND, OR, XOR, or NOT and can have one of two values, true or false.

Operator Precedence

If several operations occur in an expression, each part is evaluated and resolved in a predetermined order called Operator Precedence. Parentheses can be used to override the order of precedence and evaluate some parts of an expression before others. Operations within parentheses are always performed before those outside. Within parentheses, however, normal Operator Precedence is maintained.

Syntax

<expression> & <expression>

The <expression> represents any valid logical expression.

Whenever an expression is not a string, it is converted to a String subtype. If both expressions are Null, the result is Null. However, if only one expression is Null, that expression is treated as a zero-length string (“”) when concatenated with the other expression. Any expression that is Empty is also treated as a zero-length string.

Example

READ {.\Projects\Sample\Sample.prj}:Oswego

DEFINE FullName TEXTINPUT

ASSIGN FullName = LastName & ", " & FirstName

LIST LastName FirstName FullNam
