Format List
This section describes the notation for control statements, operators, functions, and other elements, and it also describes their
operation.
Except for comments, enter everything as single-byte characters. For specific programming examples, see "Script Programming

Execution line is executed if the conditional expression is satisfied.
; }
)
Execution line 1 is executed if the conditional expression is satisfied.
; }
Execution line 2 is executed if it is not satisfied.
; }
)
Execution line 1 is executed if the conditional expression 1 is satisfied.
; }
Conditional expression 2 is evaluated if conditional expression 1 is not satisfied,
)
and execution line 2 is executed if conditional expression 2 is satisfied.
; }
Execution line 3 is executed if conditional expression 2 is not satisfied too.
; }
)
case constant 1:
;
Execution line 1 is executed if the value of conditional expression matches constant 1.
break;
Execution line 2 is executed if the value of conditional expression matches constant 2.
case constant 2:
Execution line 3 is executed if the value of conditional expression does not match
;
constant 1 nor constant 2.
break;
default:
:
break;
Execution line is repeatedly executed while the conditional expression is satisfied.
)
The execution will go into an infinite loop when the conditional expression is always
satisfied, so do not use fixed values or devices that do not change as the conditional
;
expression.
