Variables
A variable is a symbol that holds and represents a value. Variable symbols are names such as x ,
MyVariable , or lcd.backlight . Variables can hold numbers (such as 3 or 12.7 ) or strings (such as Hello
World ).
CueServer uses two different kinds of variables: User Variables and System Variables. User variables can
be any combination of printable letters, numbers, the underscore (_) or hyphen (-). System variables are
similar, but must contain a dot (.) character. The dot character is how the CueServer distinguishes between
User and System variables.
Assigning Values to Variables
There are two ways to assign a value to a variable. The first is with the Assign command. Here are a few
examples:
"x" = 3
"MyVariable" = 42
"Message" = "Hello World"
"y" = ('x' + 3)
"caption" = "Press " + 'y' + " to Start"
The first line assigns the number 3 to the variable x . The second assigns the number 42 to the variable
MyVariable . The third assigns the string Hello World to the variable Message . The fourth assigns the result
of the expression ‘x’+3 to the variable y . The last example assigns a string made of several smaller strings
(“Press “, followed by the value of variable ‘y’, followed by “ to Start”) into the variable caption .
The second way to assign a value to a variable is with the Set command. Here are a few examples:
Set x 3
Set MyVariable 42
Set Message "Hello World"
Set y ('x' + 3)
Set caption ("Press " + 'y' + " to Start")
These examples are the same as above, except that the Set command is used instead of using the Assign
command.
