Table AM. Logical Operators

STATEMENTS

A script is made up of one or more statements. A statement is made up of a command and possibly some arguments. Each statement occupies

one line in a script, with the exception of the IF statement, which spans two or more lines. the following table lists the commands used to build

statements in VMX300(-E) scripts.

LOCAL VARIABLES: The VMX300(-E) scripting language has local Boolean variables that are declared in a script’s DIM or VAR statement. They are

local in the sense that they can be accessed only within the script that declares them, as well as from any global script the script calls using the

CALL command. They cannot be accessed from a global script run using the RUN command. Any script, global or local, can declare local variables.

Local variables have one property, Value, which is accessed [variable identiﬁer].Value. They can take values True or False, or, equivalently, 1 or 0.

OPERATOR MEANING EXAMPLE

~ unary not ~ (Date.DayOfWeek = Date.Friday)
